arch/arm/include/asm/arch-tegra*/*.h have accumulated a fair number of
unused definitions. This patch aims to delete them all.
While working on this, I noticed a few redundancies and fixed them. No
doubt other redundancies still exist simply because I wasn't looking hard
for them.
A few definitions were moved between files to allow deletion of headers.
Later changes will attempt to:
- Reduce the number of headers in the include directory.
- Move headers into arch/arm/mach-tegra/*, or into the same directory as
the drivers they serve.
- Eliminate remaining duplication.
- Refactor the headers to allow addition of future SoC support, where
those SoCs don't share many of the definitions currently located in
common headers.

Can you please get rid of this "All rights reserved." ?
Please fix this globally in the whole patch set.
I assume it cannot be a problem to do that, as in other places you did
not add this either, for example here:

Sorry, that is the format I'm required to use by NVIDIA legal.
To address your next question, "all rights reserved" is 100% compatible
with OSS licenses. Equally, the phrase already exists throughout both
the U-Boot and Linux kernel code-base (just a couple of prominent
examples) for both NVIDIA's copyright notices, and those of many other
prominent entities such as The Linux Foundation, Red Hat, Intel, The
Chromium OS Authors, etc.

The primary purpose of this patch-set isn't to clean up copyright
notices. As such, where I added new copyright notices I followed the
format that NVIDIA legal requests me to. However, where I simply edited
the date in existing notices I didn't do any other cleanup.

Yes, I know these arguments. But actually this is b*llsh*t.
Is there really no chance to drop that?

Well, obviously other people were either notrequested to add this "All
rights reserved." phrase, or found other ways to avoid it.
Can you please try to do the same?

I could ask NVIDIA legal again, but it's been discuss before and the
guidance given was not changed, so I don't imagine it would be productive.

Given that message about says "2010" as the start date, I imagine the
file was created (or copied blindly from another file that was created)
before NVIDIA legal gave guidance for us to follow. I could only do the
same by not following their current guidance, or claiming I forgot this
time, which would be rather hard to do given this email thread. Either
way, our internal systems will ding me for this when I rebase the copy
of U-Boot we use internally, so I'll have to explain it then.

Perhaps you could consider just not updating the notices? It isn't
required by U-Boot. I tend not to do it.
Also the all rights reserved thing is apparently pointless.

Simon

NVIDIA legal says I have to.
I believe the only choice I have is whether to contribute to U-Boot.
That said, I will go and double check again.

Please do go double check. Full disclosure, it's not something that's a
dealbreaker for contributions, but I'd still rather not see it be added.

The initialization performed by this code is SoC-specific not board-
specific. It also solely touches MMC controller registers. As such, it
should be part of the MMC driver itself. Move it there.

Both the change of the position of the copyright note and the
rewording contain a subtle but still significant change of meaning.
Now it seems as if Nvidia was the major copyright holder. Is this
intentional?

I was not aware that the order actually implied anything. I would
imagine the copyright dates and "git blame" output were more relevant
since they pin-point specific changes, whereas copyright headers don't
have the detail to convey the whole picture.
In this case, both "git log" and "git blame" certainly show that NVIDIA
is the primary author of this code. I deliberately removed "Portions"
because it was something uncommon and seems inaccurate. I don't recall
why I changed the order; probably because I was editing a lot of files
and just happened to paste the message there. I imagine the Samsung
copyright notice is only there because the general structure of the file
(set of functions implemented) was based on an existing driver, rather
than because any of the non-boilerplate code was written by them.
Unfortunately we've (NVIDIA at least) been a little lax making sure the
NVIDIA copyright messages are kept up-to-date when editing files, hence
why this series had to change a lot of them for the first time recently.
If we went back and re-wrote all of git history paying strict attention
to the copyright notice dates and formatting, I imagine the set of
copyright-related changes in this series would be much smaller.

Well, just read the text before and after the patch, and let the

I did not check this, and I don't intend to do so. you may actually
be right, and your modification may be perfectly OK.
But from just reading the patch, it leaves a stale aftertaste.

It is difficult for any outside party to verify this. I feel such
changes require a lot of tact, and global edits are probably not a
good idea. You know that I don't post very often lately, so you can
imagine that this must have stirred me a bit.

I'm quoting Wolfgang's email here, but, yes, keeping the copyright
notices correct is important. Now, what do you mean by would be
smaller?

Personally I want to spend my time coding rather than dealing with
licensing. As such, it's easy to forget to update the dates in copyright
notices when changing files, or to put the correct information into new
files when creating new ones (often by just cutting/pasting some other
file with similar issues). If we had done that 100% correctly in every
commit across history, my inclination is that more files would already
have an NVIDIA copyright message, and/or already have 2016 in the date,
and hence this series wouldn't include an edit to those messages since
they'd already be up-to-date. Still, I have no searched all history to
confirm that; it's just my gut instinct.

Right, OK. So you're saying you may, in some cases, be adding 2016 to
files you haven't touched this year yet?

Yes, I'm sure there's a mix.

OK. And I assume you're globbing on file paths to check / update?
Doing you can do 'git log --since=YYYY-01-01-YYYY-12-31' to find the
first/last commits in a given year, git diff a..b | diffstat > Y.txt to
get a diffstat and check your numbers vs that. This doesn't feel like
an undue burden on making sure copyright stuff is year-correct for
last-touch.

Well, by "yet" I assumed you mean "before this patch set". There are no
changes in the patch set that do nothing but edit/add a copyright notice
without making other changes. The only edits to copyrights in this
series are because I've edited files for the purpose behind the patch,
and then have updated the copyright while doing so.
What I did was:
a) Make all the changes.
b) Go through all the patches with "git rebase -i", get the list of
files edited in the patch, and ensure the copyright date reflected the
edit made in that patch.
BTW, while code re-org is not the most involved of coding, I don't see a
reason to make developers decide legal issues such as what amounts to a
change that's large enough to change the copyright date, or add a
copyright header. The rule should be simple and unambiguous (edit a file
-> change the copyright); anything else is asking for different people
to argue over interpretation, which just everybody's wastes time. Let's
leave that to lawyers and just deal with code.

OK. This should make any quick sanity checks easier, rather than
harder. Generate the lists, diffstat your series, for F in series, grep
-q year-list && echo touched $F;done

I agree in spirit, with a caveat about meeting a significance threshold.
I think you need to push back on your legal department if they are
asking that every change requires a copyright notice, regardless of
length or complexity. I _cannot_ start having patches conflict because
the contents are fine but now I have to fixup the copyright notices
added since the patch was generated, and then I suppose toss in my own
copyright too, because now I've made some change to the file. Since you
mentioned the kernel, I just popped open git log -p in the kernel and I
do not see a flood of "made a change, add/update copyright".

I'm not sure why. Let's say the two conflicting patches are both
unambiguously significant works, by two different people/entities.
Surely there's no issue with the copyright notices both being
added/updated in that case? If so, then the only difference is the
volume of conflicts. Volume doesn't seem a great argument since it's not
a problem with the core issue itself.

The problem here is that much of this series is not making unambiguously
significant changes. I do not have a problem with (but maybe I need to
chat with the Software Freedom Conservancy folks more) adding /
extending copyrights when adding significant changes to existing files
nor adding them to new files.

There is no simple rule. Adding a copyright header means you claim
your (or your company's) copyright, i. e. you are referring to legal
rules, which ar inherently non-trivial. even more so, as this is a
multi-national project - even though nternation copyright laws are
pretty much similar worldwide (there are international treaties like
the Berne convention), there may still be differences.
One area where (to the best of my knowledge - IANAL) there appears to
be agreement is that you must meet some "Creativity Requirement" with
the work you created to make it copyrightable at all.
Moving two include lines around is not really creative, and I feel sad
that we have to go into such lengthy discussions here.
Best regards,
Wolfgang Denk

tegra_mmc.h only contains private definitions for use inside the MMC
driver. Move it out of the global include directory since nothing needs
to access it there.
tegra_mmc.h doesn't depend on anything from <fdtdec.h>, so move that
include to the C file.

Machine-specific headers should be in this location. Eventually, we'll
move all headers from arch/arm/include to arch/arm/mach-tegra/include,
or find a way to delete them.

Tegra's pwm.h only contains private definitions for use inside the Tegra
PWM driver. Move it out of the global include directory since nothing
needs to access it there.

If I understand correctly, all this is just a reorganisation of code.
There is no new code or functionality added, right?

But then, you drop the original copyright notices of the Chromium
project, and replace it by a Nvidia note, and even with this
exasperating "All rights reserved" note.
Sorry, but this seems politically incorrect to me.
Best regards,

That's true in this patch, certainly.

Those copyright messages were deleted because those files were deleted.
In this case (this patch) at least, those files contained nothing but a
#include for other files.
For files that were moved (e.g. arch/arm/include/asm/arch-tegra/pwm.h in
this patch), all original copyright messages (in this case, both
Chromium OS and NVIDIA) were maintained.
I'm not aware of any deletions of copyright messages in files that were
not completely deleted, or where the same content was moved elsewhere.
If you find any, it was a simple oversight.

tegra_i2c.h contains primarily private definitions for use inside the I2C
driver. Move those out of the global include directory since nothing
should need to access them.
The Tegra I2C driver exports a Tegra-specific API. Move its prototype into
a <mach/*> header. Hopefully one day this will go away.
Tegra's SPL doesn't (yet?) support the full I2C driver stack. However, SPL
must make some I2C accesses to program the PMIC to boot the main CPU
complex (note that Tegra's SPL runs on a different CPU). Share the
implementation of those functions in a new file. This isolates the hacky
use of private register definitions to a single file.

Tegra's usb.h only contains private definitions for use inside the Tegra
EHCI driver. Move it out of the global include directory since nothing
should need to access them.
One access to these registers does exist; a boot-time cleanup of any
previous USB device-mode session. Hopefully this can be moved into the
EHCI controller probe/bind at some point, presuming that USB devices get
probed/bound at boot even before USB is used.

Tegra's dc.h/display.h only contain private definitions for use inside the
Tegra display driver. Move them out of the global include directory since
nothing needs to access it there. Since they both describe DC registers,
combine then into a single header.

From: Stephen Warren <swarren@nvidia.com>
In most current Tegra DT files, 64-bit addresses are represented in unit
addresses as a pair of comma-separated 32-bit values. Apparently this
isn't the correct representation for simple busses, and the unit address
should be represented as a single 64-bit value. Update U-Boot's DTs to fix
this issue.

Future Tegra chips contain multiple entirely separate GPIO controllers. It
is plausible that boards using those chips will end up with non-DT-driven
code that manipulates GPIOs, just like a few Tegra boards do today. In
that case, we'll want to make sure that the mapping from the global
integer GPIO numbering to GPIO controller occurs in a defined order, so
that the right GPIO is chosen in each case. To guarantee that order, GPIO
controllers must have specific DM "seq" values. This can be ensured via DT
aliases.
This is a no-op for current chips since there's only one GPIO controller.
However, it provides a good example for cargo-cult programming:-)
The aliases are added to the SoC DTSI files since there is no need for
them to vary between boards, and doing so avoids having to duplicate the
entry in each board's DT file. Any additional board-specific GPIO
controllers can be referenced by additional aliases (starting at 1) in
board DT files if needed.

TEGRA_PORTS_PER_BANK and TEGRA_GPIO_PORTS represent the same thing.
TEGRA_GPIO_PORTS is more widely used, so replace all usage with that,
and remove the redundant definition.

Do you really think that moving around two lines of code is a big
enough creative achievement to justify adding a copyright note on it?
And even with "All rights reserved."?
I stop reviewing this patch set here. I'm sorry, but I really dislike
the way how it - intentionally or unintentionally - appears to be
driven by the attempt to increase Nvidias presence in copyright
claims.
This seems not fair to me, and I would like to ask you to rework this
whole patch set and be a little less aggressive in copyright claims.
Thanks in advance.
Best regards,
Wolfgang Denk

My understanding is yes; I edited the file in a non-trival way and so
NVIDIA's copyright applies to those portions. I'd consider whitespace or
spelling fixes to be trivial, but not much else. I believe there is
creative achievement in cleaning up the code-base this way.
Of course, I'm not a lawyer and I'm sure there are plenty of lawyers who
could argue either way, perhaps depending on who pays them:-)

FWIW, the purpose is to create a cleaner separate between the core Tegra
SoC support code and board/driver code, to reduce their current rather
tight coupling. The copyright changes are just correct application of
the process of editing files; something I admit we/I've been a bit lax
about in the past.

I don't see what's unfair either way. As far as I'm concerned, the
copyright notices are simply due to my following the process I must
follow. I don't believe the presence of NVIDIA's copyright notices takes
anything away from anyone else, and as I mentioned above, they seem
valid to me.

Well, do you _really_ mean that moving two ines of code a few lines up
is a non-trivial change? Sorry, but I strongly disagree here.
This is not any change where you can claim any copyright for.

Well, if I read the code before and after your changes, I see a lot of
places where new copyright notes appear in prominent places, and some
old ones are gone, or are now just an also-ran.
I do not think that this is your intention, but it is how this appears
to me, and I really dislike it. It expresses an attitude I dislike.
Best regards,

I want to echo my agreement on this point. Re-ordering includes does
not rise to the level of adding copyright/author/etc lines. This is not
the old days before various OSS projects used some sort of SCM and the
only way you could show people you did X was to have your name
somewhere.
Lawyers can argue, but projects have guidelines. I mean heck, I've see
you remind people to fix the include order in new patches. Do they need
to add an NVIDIA copyright notice too? No, of course not. Now, if your
legal department is going to say that every change you make must include
a new copyright notice, I'll be very sad and have to ask you to limit
those kind of small clean-ups to places that already have a notice on
them for NVIDIA.

I applaud re-organizing the code and making sure customer boards
continue to work. But by that same token I do not know how Siemens
would feel if I added TI notices to their platforms back when I was at
TI and cleaning up and working on the SoC side of things. So it's not
just NVIDIA legal and community folks that you need to consider here.

I know company lawyers come up with various policies and some are more
restrictive than others. Anything about the exact guidelines you can
share would be appreciated.

They're simple and I would assume quite standard:
1) When creating a new file, add an NVIDIA copyright header.
2) When performing a non-trival edit to an existing file, if it has an
existing NVIDIA copyright header, update the data, and if not, add one.
Guidance on "non-trivial" isn't given. I would take it to mean anything
other than typos and whitespace fixes.
Re-ordering your email slightly:

I can see your argument re: copyright headers in the individual files,
although again I'd echo my previous comments re: a simple and
unambiguous process being preferable.
However, I don't agree with that argument for the patch/series overall;
it's certainly a creative process with work behind it to decide upon and
implement the overall operation. But, if the changes to every individual
file are trivial and the real work is in the idea (of the appropriate
directory organization/separation) itself, there's nowhere left to
represent that. Perhaps copyright should be applied to the patch as a
whole, and represented in the patch description, rather than individual
files in this case. I don't imagine that would satisfy lawyers though,
since e.g. .tar distributions would not contain that meta-data. I wonder
if an overall README listing all copyright holders and saying "for
details, see git log" would be satisfactory to them, at least for
"cleanup style" commits.

Quoting from [1]:
4.1 Non-trivial originality (Durham)
In Durham Industries, Inc. v. Tomy Corp.,21 the Second Circuit
Court of Appeals stated that copyright?s applicability to
derivative works is subject to the limitation that ?the
original aspects of a derivative work must be more than
trivial.?
...
However, the Alfred Bell court considered non-trivial
variation to be a requirement of the originality standard, and
merely a restatement of the principle that, to be original, a
work must be ?recognizably [the author?s] own.?

Here's where I hope I don't get everyone at NVIDIA that's doing Linux
Kernel or other F/OSS work in trouble. Point #1 above is quite
understandable. Point #2 is something I can see but has totally not
been done by the folks doing Linux Kernel work.
What I do not want to see is a changing of the norms and when possible
and makes sense, a deviation from the norms of the Linux Kernel. And
that would be that you have to make a pretty huge change (at which point
for maintainability and refactoring and so forth, it's probably a new
file or set of new files) to add a Copyright line to an existing file.
But we're not the kernel, true. But looking over the current changes
for the year, same thing.
Now, if you want to instead make the point that in various cases fileB.c
is based heavily on fileA.c and the copyright was missing on fileA.c
when fileB.c was made, that makes sense. Or if they dropped the
copyright line (and we assume no malice), add it back in.
But I do not want to see the threshold for "add your copyright to a
file" be set at "made a non-whitespace/non-typo change".

The review on this patch series itself has indeed been derailed, which I
do not like either. With respect to copyright on individual changes and
so forth, is this a concern you have, or a concern the lawyers at NVIDIA
have?

Admittedly compliance is spotty; the last thing someone wants to do when
having completed a patch is think about all kinds of nit-picks like
updating copyrights, checkpatch, testing, even compiling:-)
However, it's certainly not unheard of. Here are a few examples I was
able to spot quickly:
NVIDIA:
af6313d61a78 (Alex Courbot)
08acae34e8da (Paul Walsmley)
891846516317 (Thierry Reding)
783c8f4c8445 (Peter De Schrijver)
0ffdd4b61b13 (Stephen Warren)
Red Hat
1363074667a6 (Hans De Goede)
25462f7f5295 (Wei Huang)
54cea3f6681a (Milan Broz)
Texas Instruments
2f67864b6d5b (Andrew F. Davis)
0d6fa53fd805 (Andy Gross)
Denx
88eeb72ec4c1 (Stefan Roese)
Admittedly those don't look like refactoring changes, but it sounded to
me like you were arguing completely against point (2) in my original
email above. That's not reasonable. Arguing against (2) for simple
refactoring could be.

The lawyers have dictated the process which I should follow. I often
forget, so I made sure that for such a large series I'd follow the
process correctly this time. To be honest, I'm way beyond care about
anything to do with copyright at this point; I'd rather just work on
something where it wasn't an issue in any form at all.

I'm arguing in favour of what all of those commits did, extending
existing copyright notices. I'm fine with that. To be clear, in _this_
patch what I object to is adding the NVIDIA copyright line to
board/avionic-design/common/tamonten-ng.c and I am fine with extending
it on all of the board/nvidia/ files and now wondering you didn't add it
to board/toradex/.

Well honestly all patch review does contribute to the creative process
and affect the final result, so I don't actually think it'd be that much
of a stretch that a reviewer's copyright applies to the final patch;
they were involved in the creation of it. Perhaps Reviewed-by tags or
the mailing list history would be enough evidence of this though, if
such were needed later.

And this is why I love patchwork and hope that as it starts to handle
series more directly it will also handle "For the series, ..." messages
in addition to collecting up Acked/Reviewed/Tested by lines. These are
important for history of changes to the codebase.

the redundancy by replacing everything with the DT binding header file.

Tegra's gpio.h contains a mix of private definitions for use inside the
GPIO driver and custom machine-specific APIs. Move the private definitions
out of the global include directory since nothing should need to access
them. Move the public definitions to the machine-specific include
directory <mach/>.

This seems a bit ugly. Perhaps you could havestruct
gpio_ctlr_high_regs and include that here? It adds a level of
indirection but that doesn't seem very important.

In newer Tegras, there's no differentiation between the two register
sets that were "low" and "high" in Tegra20. I'd rather not saddle the
non-Tegra20 struct layouts with some odd naming/nesting just because the
Tegra20 layout was odd. I don't see any problem with using a #define for
this; it doesn't seem to make the code complex.
I wonder if we should just convert away from structs for registers
entirely. Everything in the HW docs is just numbers, matching those to
the structs is always painful, and if we used #defines instead of
structs, representing this HW difference would end up being much cleaner
and avoid using a macro to "cut/paste" a register list 2 times; see the
way the Linux kernel driver handles this.

OK, well then how about just duplicating the two structs, and dropping
the #define?
#ifdfef CONFIG_TEGRA20
struct gpio_ctlr_bank {
};
#else
struct gpio_ctlr_bank {
};
#endif

Structs are definitely easier to read and particularly in this case
where each struct element is an array.
Why are you worried about code duplication in a header file?

Given that the driver doesn't use any registers in the high bank, and
indeed can't; the driver's reliance on structs rather than register
defines means that the high bank registers would have to be accessed
differently between Tegra20 and other SoCs, I propose simply not
representing those registers. Instead, how about:
struct gpio_ctlr_bank {
uint gpio_config[TEGRA_GPIO_PORTS];
uint gpio_dir_out[TEGRA_GPIO_PORTS];
uint gpio_out[TEGRA_GPIO_PORTS];
uint gpio_in[TEGRA_GPIO_PORTS];
uint gpio_int_status[TEGRA_GPIO_PORTS];
uint gpio_int_enable[TEGRA_GPIO_PORTS];
uint gpio_int_level[TEGRA_GPIO_PORTS];
uint gpio_int_clear[TEGRA_GPIO_PORTS];
#ifndef CONFIG_TEGRA20
uint unused[TEGRA_GPIO_PORTS * 8];
#endif
};
struct gpio_ctlr {
struct gpio_ctlr_bank gpio_bank[TEGRA_GPIO_BANKS];
};
That removes all the duplication, without any macros etc.
Does that look reasonable? If I fixup the patch like that, I'll add a
brief comment describing what the unused registers are, similar to the
one in patch v1.

I'm not really sure there's much objective difference between the
readability of the two. Arrays can easily be abstracted via a macro or
inline function so that the call site looks essentially identical; () vs [].

I'm not sure why I would special case my concerns and ignore duplication
in certain locations yet still care about duplication in general or
elsewhere?

IMO the code is much harder to follow when you need to look up macros,
etc. C already supports arrays :-)

We commonly put ugliness in header files. So long as the resulting
syntax (in C files) is pretty obvious and non-surprising, this makes
sense. Most of the time these header files are ignored by humans when
reading the code since it is pretty obvious from the C code what is
going on.
Examples include static inline to drop functions, hardware register
definitions, bitfield definitions, #ifdef setup (see image.h), etc.
Perhaps by that argument your original #define scheme is fine. I don't
like things that make it hard to grep the code for stuff, but this is
minor. So I'm going to withdraw my objection (sorry).

All configuration is migrating to Kconfig. This moves one piece.
TEGRA_GPIO is default y since it's almost certain to be needed, and this
setting matches the stanza removed from the config header file.
CONFIG_HAS_TEGRA_GPIO is introduced so that drivers/gpio/Kconfig doesn't
have to know which Tegra chips contain this GPIO controller, thus
isolating such knowledge into mach-tegra/Kconfig. All currently supported
chips do, but the next chip contains a different GPIO controller and hence
requires a different driver.

This header is only needed by code local to mach-tegra/, so move it there
to avoid polluting the global include path.

Yes:-P

As mentioned in the commit description, the content of the header is
only used by code in arch/arm/mach-tegra/. By moving the header file out
of a directory that's part of the include path, we ensure that code
(such as drivers and core code) can't access the header without
explicitly doing something unusual, which should ring alarm bells. This
will help avoid future additions of code that touches Tegra internals
rather than accessing functionality through standard/generic (or even
custom but explicitly "exported") APIs.

Well if that's what you want, OK.
The ../xxx.h looks odd to me - like a temporary hack. Also if we have
a driver for SoC functionality then it will likely need access to this
stuff. But I can't see a better way to do this, and it does achieve
your goal...

Thanks.
If we do end up with a "real" driver for this in drivers/xxx/, I would
hope the register header would move into the same directory along with
the C file so nothing else could access it, and other code would only
access those registers by calling functions in the driver, those
functions being prototyped in some public header file in include/ or
arch/arm/mach-tegra/include/mach/ depending on whether the API was
U-Boot-wide or Tegra-specific.
This current patch does mean if we get a driver, we'll have to move the
header again, but I don't expect that to happen imminently (perhaps
ever?) for most of the code in arch/arm/mach-tegra, with the possible
exception of clock/reset/XUSB drivers. Equally, there would be so much
change involved in converting everything not to access the register
directly but instead use clean APIs that including a header move as well
would likely be close to noise.

Machine-specific headers should be in this location. Eventually, we'll
move all headers from arch/arm/include to arch/arm/mach-tegra/include,
or find a way to delete them.

Machine-specific headers should be in this location. Eventually, we'll
move all headers from arch/arm/include to arch/arm/mach-tegra/include,
or find a way to delete them.
Both board and sys_proto.h served the same purpose; a place to prototype
functions implemented by the board and called by code in mach-tegra/.
Merge them into a single file to reduce the number of headers.
board_init_uart_f() is private to code in mach-tegra/ so remove its
prototype from the public <mach/> header. cpu.h isn't a great place for
it, but other functions implemented in the same C file are prototyped
there, so it'll do for now. When the C files are all refactored for
Tegra186, this should be cleaned up.

This header is only needed by code local to mach-tegra, so move it there
to avoid polluting the global include path.
tegra_set_emc() is moved between two emc.h so that mach-tegra/emc.h
defines fairly public interfaces to the EMC functionality, and emc_priv.h
contains internal register details.

This header is only needed by code local to mach-tegra, so move it there
to avoid polluting the global include path. Also, unify the 3 identical
copies of the file into one.

This header is duplicated many times, and does nothing but prototype a
single function that's used solely by mach-tegra code. Move the proto-
type of mach-tegra/cpu.h. That's not an awesome location for it, but
other similar functions like pmic_enable_cpu_vdd() are already there.

I wonder if it would be better to retain the header name and move
pmic_enable_cpu_vdd()?

I think that pmu_set_nominal() (the function moved into cpu.h by this
patch) and pmic_enable_cpu_vdd() serve essentially the same semantic
purpose, but are used on different sets of SoCs via ifdefs or weak
functions. I expect that early in the part 2 series, I'll get rid of
more code in board2.c's board_init() and put it into something like
tegra_board_init_soc(), prototyped in board_init.h or soc_init.h.
Or put another way, I expect I'll clean up the "not a great location"
issue mentioned in this patch description pretty soon.

Machine-specific headers should be in this location. Eventually, we'll
move all headers from arch/arm/include to arch/arm/mach-tegra/include,
or find a way to delete them. This change also removes multiple useless
empty wrappers for this header.

Add arch/arm/mach-tegra/tegraNNN/include. We'll use this to house headers
that must vary between SoCs (e.g. clock lists, register layouts that
aren't static across chip versions, etc.) in a <soc/> name-space. This
will allow code in mach-tegra/ to access those register definitions without
polluting the more public <asm/> or <mach/> namespaces or the directories
they map to.

According to the TRM, Tegra20's flow controller has a xrq_events field
too. Suspend/resume (via LP0) does still work after this fix, implying
the write to halt_cpu1_events in warmboot_avp.c isn't actually necessary,
since this patch causes it to access a different register.

This header is only needed by code local to mach-tegra, so move it there.
Since the definitions are used by code in mach-tegra/ itself, not just in
SoC-specific mach-tegra/tegraNNN/, and the content varies per SoC, we need
to put it in the (somewhat isolated) <soc/> include directory rather than
in mach-tegra/ directly.

Equivalent code is already present in the core Tegra board file, so
there's no point repeating it here. This removes the only use of
<asm/arch/mc.h> from outside arch/arm/mach-tegra/.

This header is only needed by code local to mach-tegra, so move it there.
Since the definitions are used by code in mach-tegra/ itself, not just in
SoC-specific mach-tegra/tegraNNN/, and the content varies per SoC, we need
to put it in the (somewhat isolated) <soc/> include directory rather than
in mach-tegra/ directly.

These defines are used with APIs in pinmux.h, so it makes sense to put
them into the same header. It also allows all includes of gp_padctrl.h
to be removed from code outside arch/arm/mach-tegra/.

From: Stephen Warren <swarren@nvidia.com>
U-Boot is compiled for a single board, which in turn uses a specific SoC.
There's no need to make runtime decisions based on SoC ID. While there's
certainly an argument for making the code support different SoCs at
run-time, the Tegra code is so far from that possible ideal that the
existing runtime code is an anomaly. If this changes in the future, all
runtime decisions should likely be based on DT anyway.

What exactly is missing to prevent multi-arch support? Shouldn't we
head towards that rather than making it harder?

In a word: everything:-)
Pretty much all decisions in core architecture code, core Tegra code,
drivers, and even board files are currently made at compile time. For
example, consider drivers where the register layouts are different
between different SoCs; not just new fields added, but existing fields
moved to different offsets. Right now, we handle this by changing the
register struct definition at compile time. To support multiple chips,
we'd have to either (a) link in n copies of the driver, one per register
layout, or (b) rework the driver to use #defines and runtime
calculations for register offsets, like the Linux kernel drivers do.
Tegra USB is one example. The pinmux and clock drivers have a
significantly different sets of pins/clocks/resets/... per SoC, and
enums/tables describing those sets are currently configured at compile
time. Some PMIC constants (e.g. vdd_cpu voltage) are configured at
compile-time, and even differ per board.
> Shouldn't we head towards that rather than making it harder?
I don't see any need for that, no.
U-Boot is built for a specific board (or in some cases a set of
extremely closely related set of boards, such as the RPI A/B/A+/B+).
There's no need to determine almost anything at run-time since almost
all information is known at compile time, with exceptions such as
standardized enumerable buses such as USB, PCIe. If we support multiple
HW in a single binary, it gets bloated with code that simply isn't going
to be used, since all the extra code is either for a platform that the
build won't be installed on (e.g. clock/pinmux tables), or is overhead
to add runtime detection of which block of code to use, which simply
isn't needed in the current model.
In my opinion, firmware/bootloaders run on a single specific board,
whereas full-featured operating systems support multiple systems.
As an aside, I've wondered whether U-Boot should be split into multiple
parts; one HW-specific binary providing various drivers (e.g. via
DM-related APIs?) and the other containing just high-level
user-interface code such as the shell, high-level USB/... protocols,
which would only call into those APIs. Still, I don't think we're
anywhere close to that, and I'm not aware that it's a goal of the
project at the moment.

I wonder how far we would get by converting clock, pinctrl, reset to
driver model drivers?

It's not so much that. Presumably a build for a particular board would
not include support for and SoC it doesn't have. But it is still
useful to build the code. For example it would be nice to have an
overall Tegra build that enables all SoCs to avoid building every
board.
So it is a serious question. I suspect the main impediment may be
moving the clock and other core stuff to driver model.

Except when the boards are pretty similar. Also, doesn't barebox have
only one build for Tegra?

Well it gets built as one binary, but there's a pretty clear
separation in the code, at least with driver model. What's the purpose
of this?

Well, I expect we'll find out soon. The next SoC has radically different
clock/reset mechanisms, so we'll need to switch to standardized APIs for
clock/reset on Tegra to isolate drivers from those differences, and I
imagine that conversion would also involve conversion to DM since any
standard APIs probably assume use of DM. I haven't investigated this in
detail yet though.

Yes, everything is a bit too tightly coupled at the moment, and in many
cases each SoC-specific implementation exposes the same global symbols
which clients use. DM or similar conversions may well solve a lot of this.

I haven't looked at Barebox much. IIRC it only supports Tegra20 and not
later SoCs which could simplify things. Besides, I'm not arguing that
it's impossible to make a unified binary, simply that I don't see any
need to do so, except perhaps your compile-coverage suggestion.

It would allow the HW-agnostic portion to be compiled once (or once for
a CPU ISA) and re-used with any of the HW-/board-specific "driver"
blobs. It'd get use to "single binary" for the generic stuff, but
without requiring the for HW-specific code. Perhaps the generic portion
could even run on top of other driver stacks if they implemented the API
it needed! However, this does ignore potential feature differences in
the common binary, e.g. someone might want dfu/ums commands, but someone
else might not need them and hence consider them bloat. Still, those
configurations would be differentiated by feature more than HW, so it
might still be useful.

With a suitable API (even it if is pretty basic) the coupling can
often go away. The current driver-model pinctrl/clock APIs are pretty
simple, but they are effective in this regard for the SoCs I've tried.

Sure. I think it might help push the APIs along though. I recall
creating a clock API for tegra20 some years ago. I think if we go to
the next level (clock drivers for each SoC) the SoC differences start
to look a lot less. It's mostly this core code that is the problem and
much of it should move to drivers IMO.

Sounds cool. It would certainly tidy up the U-Boot API a lot, I
suppose. You could have a micro-module approach where every little
feature is its own loadable module. But really, what is the benefit?

Sorry, I still feel this is going in the wrong
direction...CONFIG_TEGRA124 should mean that the code supports it,
rather than the code exclusively supports it.
In your commit message you say:
"While there's
certainly an argument for making the code support different SoCs at
run-time, the Tegra code is so far from that possible ideal that the
existing runtime code is an anomaly. If this changes in the future, all
runtime decisions should likely be based on DT anyway."
Or even build time.... That statement seems like saying that
everything is so terrible that we might as well give up.
What's your plan to move code into drivers? I am happy to help move
things over and get towards the goal rather than further away. But
really that should happen first.
Also, the model that seems to be emerging is that SPL detects the
platform and passes the correct DT to U-Boot proper.
Specifically I think the end state should be:
- Most SoC code is in drivers using driver model
- It is possible to build most of the tegra code without building each
SoC (just by having a 'tegra' board which enables all drivers)
- If someone wanted to support multiple SoCs it would not be
impossible to do so (even if mainline doesn't make it)
- New SoCs are supported mostly by adding new drivers (although there
is always of course some core/start-up code)
Do you agree with that?
Regards,
Simon

And just to be clear, I'm always keen to move things forward and I can
see you have put a lot of work into this series. It would be easier to
just apply it as is. What I am looking for is how we might get closer
to the goal, perhaps after this series. This series has exposed this
which is why I have brought it up.

So, just to be clear: TomW can apply this (once I post V2) even if
you're not giving an ack?

That's certainly not what it means right now, and my intention in this
series was not to address any short-comings in the current meanings of
Kconfig.
No matter what, if we do drive all this core SoC code from DT
eventually, I don't imagine tegra_get_chip() will be the way code gets
dispatched between multiple chips in the future, so removing it now
shouldn't hurt any later conversion to runtime multi-chip support.
In practice in a DT-driven world, I'd expect:
- The code in enable_scu() to be part of some Tegra20-specific "SoC
driver" or similar, and hence not need any runtime support restored.
- The code in cache.c to be part of some specific cache drivers, which
would only be instantiated on Tegra20, and hence not need any runtime
support restored.
- The code in cpu.c to be moved into a clock driver, and base on some
per-SoC table in the clock driver, and hence not need any runtime
special-casing.
As such, I don't see reverting any of this patch being reverted later,
and I don't believe leaving in these runtime calls would make it any
easier to refactor the code into drivers later.

I'm just being practical. Please note in particular the comment about
basing such decisions on DT; that and refactoring the code into
DT-instantiated drivers would leave it so different that the tiny number
of current runtime switches doesn't help anything.
>> What's your plan to move code into drivers? I am happy to help move

>> really that should happen first.
I don't have a plan for anything besides the clock and reset drivers at
the moment. I /think/ that most of the rest of the code in
arch/arm/mach-tegra simply won't be needed on Tegra186. We'll see; I
only have UART and GPIO working right now, well and a very hacked-up MMC
to avoid clock/reset access. There is a large amount of work left that I
haven't started looking at yet.
>> Also, the model that seems to be emerging is that SPL detects the

There is no SPL on Tegra210 or later. It would be a pity to have to
introduce one just to do runtime DT selection when there's no need to
have runtime DT selection.
>> Specifically I think the end state should be:
>> - Most SoC code is in drivers using driver model
That is fine in many cases. There's plenty of low-level bootstrap code
where I'm not sure that it's worth it. Equally, given that you have
stated DM==DT, I worry about the implications of that statement if
universally applied, rather than selectively/pragmatically applied.
>> - It is possible to build most of the tegra code without building each
>> SoC (just by having a 'tegra' board which enables all drivers)
I'm not convinced this is worth it universally.
For the purposes of actually running a binary on a device, I believe
there is zero need for this.
For compile coverage it might be nice, especially for driver code,
although running buildman on one Tegra board for each SoC generation
doesn't take much time.
Even for drivers that solely use generic (non-SoC-version-specific)
APIs, this would be difficult in some cases. This plays back into my
earlier comments elsewhere about structs-vs-defines for register address
calculations. Register layouts of some devices vary incompatibly between
Tegra SoC generations. With a define-based driver, this can all be
handled at run-time. With a struct-based driver, one must compile the
code once per register layout. Rather than invest in making a "compile
test" build that does this, which would require various build system
work, it's much simpler to just compile the driver multiple times as
part of a set of board builds, which already works today. The result is
still compiling the code n times, so there wouldn't be much time saving
wrapping everything into one build.
>> - If someone wanted to support multiple SoCs it would not be
>> impossible to do so (even if mainline doesn't make it)
I don't think it's a good idea to support features that mainline doesn't
use. They'll bit-rot and not work anyway. I also can't see any use-case
for such a build.
>> - New SoCs are supported mostly by adding new drivers (although there
>> is always of course some core/start-up code)
Yes, it certainly makes sense to use drivers for functionality which
other pieces of the code must interact with in a generic way. For
example, calls from I2C/MMC drivers to clock/reset APIs.
I expect some debate over what code is core/start-up code though. For
example, static pinmux setup fits that category for me, since there's no
generic code that needs to interface with it.

Provided you are OK with using drivers for clock, pinctrl etc. with
your new Tegra work. I'd really like to move away from all this code
in arch/arm, private APIs, etc..

Well it means that in quite a few places - e.g. this one that you are removing.

Sounds reasonable. So long as we are agreed on using drivers then I am
OK with it as a means to an end.

Right, but you are actually removing functions that detect the SoC.
That is surely heading the wrong way.

How does the platform start up? Does it use BCT and then jump straight
into U-Boot?

I have not stated that DM==DT. Where there are reasons to use platform
data we can do that. See this comment in the driver-model README:
*** Note: platform data is the old way of doing things. It is
*** basically a C structure which is passed to drivers to tell them about
*** platform-specific settings like the address of its registers, bus
*** speed, etc. Device tree is now the preferred way of handling this.
*** Unless you have a good reason not to use device tree (the main one
*** being you need serial support in SPL and don't have enough SRAM for
*** the cut-down device tree and libfdt libraries) you should stay away
*** from platform data.
This is a boot loader. We need to be pragmatic. This is why I push
back on core driver-model code bloat.

Well your hardware guys really should make up their mind. Is there any
code review? And s/w people should have a system (with serial driver)
running before tape-out and catch this stuff.
But in any case, struct-based stuff is not a requirement now. I
believe a lot of people prefer it (including me) but in the case you
raise it isn't practical. See ns16550 for how this can be done badly.

While SoC vendors think of the SoC as a the most important factor in
the platform, we are starting to see similar devices using different
SoCs, or at least different variants. From a user point of view I'd
rather not worry about which Raspberry Pi I have, for example, so long
as I can build something that boots.

So please put your pinmux code in a pinctrl driver, even it is just in
the probe() method.
Also I have a Tegra124 platform now. Once the smoke has cleared with
your work I'd like to take a look at how to improve things.

U-Boot is compiled for a single board, which in turn uses a specific SoC.
There's no need to make runtime decisions based on CPU count. While
there's certainly an argument for making the code support different SoCs
at run-time, the Tegra code is so far from that possible ideal that the
existing runtime code is an anomaly. If this changes in the future, all
runtime decisions should likely be based on DT anyway.

The only place this is still used is Tegra20's warmboot.c. Keep the T20
copy around for that use, but remove the other unused duplicates.

EMC scaling is specific to Tegra20. Move the code into tegra20/ to isolate
it. If it becomes more generic in the future, it should likely be moved
somewhere in drivers/, but at the least be reworked to have a leaner and
cleaner interface to its caller (i.e. fewer dependencies, interactions).

Rather than building a large table of all possible PLLX configurations
into U-Boot and having it select the right one at run-time, push the
configuration into SoC-specific files, and have the linker pick up the
correct one.

This is now only used by some Tegra20-specific code, and only to select
between T20/T25 code paths. Introduce a simpler function for that case,
and isolate it to the tegra20/ directory.
If we need SoC differentiation in the future, we should isolate the SKU-
specific logic to the SoC-specific directories, and provide a higher level
interface that the SoC-agnostic code can use; similar to pllx.h in the
previous commit.

From: Stephen Warren <swarren@nvidia.com>
The existing funcmux APIs have the disadvantage that clients call a single
monolithic/IOCTL-style function which performs different operations based
on its parameter. All branches of that function are always compiled into
the binary even when they're not used.
Another disadvantage is that funcmux is pinmux functionality, but
implemented outside the Tegra pinmux driver.
This patch creates a separate function per operation, and implements them
as part of the pinmux driver. Later patches will convert callers to these
functions and eventually remove the funcmux files.

This should go in a pinctrl driver for each SoC.

From: Stephen Warren <swarren@nvidia.com>
Currently, SPL console initialization on Tegra suffers from two problems:
1) It's a monolithic function that knows about all possibilities using
tables and ifdefs set by board config.h, and contained in core files that
are always built into U-Boot. Some of the code can't be ported to future
SoCs since the clock APIs will be different. Equally, future SoCs don't
need the code since earlier boot FW will always initialized the UART.
2) It's unnecessarily invoked twice, once by SPL and once by the main
U-Boot binary.
This patch adds simpler APIs to initialize the UART from SPL. This code
can be omitted from non-SPL builds.
A future patch will add the code to the Makefile when board files are
converted. Adding it now would cause duplicate symbols for the UART
device itself which will cause the link to fail. Even if that were
resolved by changing the symbol name, duplicate UART devices would be
registered, which would likely cause runtime problems.

From: Stephen Warren <swarren@nvidia.com>
Tegra's board2.c and spl.c implement the core U-Boot board initialization
hooks, and call a variety of other functions to initialize the system,
some of which are implemented by board-specific code. board2.c and spl.c
currently call a large variety of "hook" functions that boards can
customize, one per type of action that might be performed by a board. This
isn't very scalable, and leads to a lot of ifdefs in board2.c. This patch
creates yet more functions that board2.c ans spl.c will call, with the aim
that all other functionality will be migrated into those functions.
The new functions are added to a new header file to make it more obvious
which are "the new way" and which will eventually go away (board.h).
Two simple one-off cases are immediately converted to the new functions,
and the old functions removed. Other functions require a bit more work
and will be converted by separate patches.

Implementations of the following functions are converted to use the new
standardized hooks: gpio_early_init, gpio_early_init_uart, pinmux_init,
board_init_uart_f. This simplifies the core board files.
SPL UART configuration is moved out of config headers and into board code.
This removes logic from the board configuration files.
The now-unused board_init_uart_f() implementation is deleted, simplifying
the core board files and removing code that's hard to port to future SoCs.
Whitespace was removed from tegra_board_early_init_f() to save space and
be consistent between boards.

From: Stephen Warren @ 2016-04-19 20:59 UTC (permalink / raw)
To: u-boot
From: Stephen Warren <swarren@nvidia.com>
Implementations of the following functions are converted to use the new
standardized hooks: pin_mux_usb, pin_mux_spi, pin_mux_nand, pin_mux_mmc,
pin_mux_display. This simplifies the core board files.
For some boards, function sort order was changed so that functions appear
in they order they're called.

Remove funcmux calls from the Tegra keyboard driver. Knowledge of pinmux
setup must come from either board files or DT; it should not be embedded
into board-agnostic driver code. The DT pinmux bindings do not allow
drivers to derive funcmux-style information, since the DT bindings are
pin-based whereas funcmux is controller-based, so there's no good way to
call the existing funcmux APIs from drivers. Converting drivers to use a
new (as yet non-existent in U-Boot) API that pulls pinmux information from
DT isn't useful for Tegra, since Tegra's DT files don't contain any
per-device pinmux tables, so this would simply be extra code that has no
effect; doesn't actually set up the pinmux. We are left with moving the
pinmux setup functionality into board files. In theory the board files
could be converted later to use DT, but that would be a separate change.

With a pinctrl driver this can happen automatically, or you can load
your single table in the probe() method.

Remove funcmux calls from the Tegra20 video driver. Knowledge of pinmux
setup must come from either board files or DT; it should not be embedded
into board-agnostic driver code. The DT pinmux bindings do not allow
drivers to derive funcmux-style information, since the DT bindings are
pin-based whereas funcmux is controller-based, so there's no good way to
call the existing funcmux APIs from drivers. Converting drivers to use a
new (as yet non-existent in U-Boot) API that pulls pinmux information from
DT isn't useful for Tegra, since Tegra's DT files don't contain any
per-device pinmux tables, so this would simply be extra code that has no
effect; doesn't actually set up the pinmux. We are left with moving the
pinmux setup functionality into board files. In theory the board files
could be converted later to use DT, but that would be a separate change.

This should use driver model, which handles pinmux automatically if
you have a pinctrl driver.

Can you define "automatic"? I don't understand exactly which benefit
you're describing there.
I'd rather keep this series as simple cleanup of existing code, and
handle any large-scale DM conversions separately later. That said, as
full disclosure, I'm certainly not signing up for any more work on
pinctrl, especially if it involves reading the pinmux tables from DT, as
I see no benefit in that. Note that in future chips the boot ROM will
handle 100% of static pinmux setup so there won't be a U-Boot driver for
those SoCs going forward. I'd rather not invest any more than minimal
effort in something that's going away.

When you probe a device, its pinmux is set up automatically, so the
explicit funcmux calls can go away.

There's no need for it to read from DT, and it doesn't have to be
comprehensive but I think you should create a pinctrl driver and put
the funcmux stuff in that (along with processing your big tables of
pinmux stuff).

So the device here would be the pin controller device itself, not
individual I2C/SPI/SD/... devices.
That's because the Tegra HW does not support[1] dynamic or partial
pinmux configuration. As such, we need to program the entire pinmux at
once early during boot, not piece-by-piece as the individual U-Boot
devices that use individual pins are probed. This is why for example the
kernel DT contains a single pinmux table that the pin controller driver
sets up at boot (with identical configuration to what U-Boot sets up, so
it's a no-op), rather than splitting it into per-device chunks.
As such, there isn't any need for, say, an I2C device probe to call into
pinmux at all; the pinmux would already have been set up entirely during
early boot, and hence no I2C-specific actions would be needed later.
So I'm not sure what benefit conversion to DM pinctrl has here. Sure it
means things get set up the same way as with any other pinctrl device or
SoC, but this is early SoC-specific configuration, without any
interaction with common or driver code besides being implemented via
some standard core->board callbacks/hooks. It seems reasonable to just
program the pinmux directly using SoC-specific APIs rather than having
to add a layer of abstraction on top of it just so we can route it
through DM. In other words, what's already done by this patch series.
Besides, I believe the programming happens before a DM pinctrl device
would be ready, doesn't it, given it happens from
tegra_board_early_init_f()? Or, would we be able to fully probe a DM
device at that point? The UART console setup is even earlier, in SPL
pre-T210, where I don't think we even have DM enabled.
[1] Yes, the HW registers can in practice be programmed bit-by-bit,
simply because there are a number of registers and the SoC doesn't have
a way to physically force SW to write to each of those registers.
"Support" here refers to what the ASIC team will guarantee will work
correctly without causing glitches or similar issues. There are a few
limited exceptions, e.g. console UART muxing on its own has been at
least partially thought out (although there are still conflicts in some
cases on older chips), and IO controllers that may contain boot media
are generally OK to mux on their own. However, for anything else, i.e.
the majority of cases, the supported model is to program everything
up-front in one go, and not change it later. Sticking to that general
model in absolutely all cases removes special cases and simplifies the code.

Is this the big table that I see in device tree files?
pinmux at 0,70000868 {
pinctrl-names = "default";
pinctrl-0 = <&pinmux_default>;
pinmux_default: common {
clk_32k_out_pa0 {
nvidia,pins = "clk_32k_out_pa0";
nvidia,pull = <TEGRA_PIN_PULL_NONE>;
nvidia,tristate = <TEGRA_PIN_DISABLE>;
nvidia,enable-input = <TEGRA_PIN_ENABLE>;
};
...

OK. As you know I don't like this monolithic pinmux stuff - at least
in early boot it is useful to enable (say) just the UART. Anyway I
still think a driver is useful and will provide a better base for the
future.

DM is enabled pretty early, before board_early_init_f(). But if you
hit a problem we can look at it. There is no point in setting up
pinmux before driver model, since it is the drivers that use it.
Worst case, how about creating a pinctrl driver where everything
happens in the probe() method? Ideally you could do the minimum
necessary before relocation, and then the full table load afterwards.

Every SoC has its limitations in terms of pinmux. The point here is to
have a sensible API on top of this stuff. At least then people know
where to find the code, and all the pinmux hacking is in one place.
Yes Tegra has some special features, but Linux has a pinctrl driver
for Tegra. Can't U-Boot?

Simon

Replace all usage of funcmux APIs with the pinmux functions previously
added to replace then. Delete the funcmux implementation since it's no
longer used. This merges all pinmux-related logic into the pinmux code
and avoids use of the funcmux "IOCTL" functions, which compile in
support for all possible pinmux options even when they won't ever be
used by a particular build.

The concept is fine, but this should use a pinctrl drive.r

The only use of the BIT was to print a message indicating whether the
system booted via cold boot or USB ReCovery Mode (RCM). If that is worth
doing for some boards, it's worth doing for all, so make the core Tegra
code do that.
This will allow the definitions related to the BIT to be removed from
global visibility, and isolated into Tegra-specific code. This also avoids
the need to implement arch_misc_init() for a couple of boards.

Most of arch/arm/include/asm/arch-tegra*/tegra.h is only used by code in
arch/arm/mach-tegra, so move the header files there to avoid polluting the
global include path. While moving, unify the per-SoC files into one using
a couple of simple ifdefs; this avoids having so many headers.
Many source files relied on <common.h> including the board config.h file,
which in turned used to include tegra.h. Now that we've removed this, we
need to include tegra.h from those files, hence this patch adds a few new
include statements.
A few defines from tegra.h are used by code outside mach-tegra. These are
dealt with as follows:
- A few drivers program clock registers directly and hence use
NV_PA_CLK_RST_BASE to locate the registers. Move this into clk_rst.h; that
makes sense since it defines the register layout and may as well define
the address too. Later patches will hopefully clean up the Tegra clock
driver and hide this information too.
- Various other definitions are used by the board config headers and/or
core U-Boot code (e.g. ARMv8 boot assembly). These can't include
SoC-specific headers from <mach/>. Hence, move those definitions into
tegra-common.h so they're generally available.

These are the last files in arch/arm/include/asm/arch-tegra*. Move them
into arch/arm/mach-tegra. The Tegra clock API currently exposes a lot of
internal implementation details, which are unfortunately relied upon
throughout the code base. Consequently, the headers are moved to <mach/>
rather than being hidden out of the global include path. This needs
cleanup/refactoring, especially since the current state cannot support the
next chip at all. However, this cleanup series is already rather long, and
the work to cleanup the clock API rather involved, so I'll do that later.

I've reviewed the reset of the patches. It is a huge improvement in
the tegra code. It's more consistent and fixes up some of the weird
code placement and muddy concepts.
If there are any patches I am missed, let me know.
My main comment is that the pinctrl stuff should go in a driver. There
is not way we should be inventing a new pinmux API for tegra now that
we have driver model pinctrl :-)
I am happy to help with this if you like.
Regards,
Simon
