This is the first set in my ux500 multiplatform series.
As you can see it starts out by getting rid of three
files in <mach/*>. It's enough stuff to discuss already,
and relates to my recent question of whether the mailbox
subsystem can be merged into the ARM SoC tree.
Linus Walleij (6):
ARM: ux500: move debugmacro to debug includes
clk: ux500: pass clock base adresses in init call
mfd: prcmu: pass a base and size with the early initcall
mfd: db8500-prcmu: get base address from resource
ARM: ux500: move PRCMU functions into the CPUidle driver
ARM: ux500: get rid of <mach/[hardware|db8500-regs].h>

This moves the Ux500 debug macro to the debug headers to
make way for multiplatform support.

The ux500 clock driver was including <mach/db8500-regs.h>
which will not work when building for multiplatform support
since <mach/*> is going away.
Pass the base adresses in the init call instead.

Requesting an ACK from Mike on this to merge it through
the ARM SoC tree eventually.

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.

From: Linus Walleij <linus.walleij@linaro.org>
We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The CPUidle code is
calling down into the PRCMU driver basically just to access
these registers, so let's remap them locally in the CPUidle
driver and move the code there, simply. Besides, the PRCMU
code was poking around in the GIC which is the responsibility
of the machine.

This removes <mach/hardware.h> and <mach/db8500-regs.h>
from the Ux500, merging them into the local include
"db8500-regs.h" in mach-ux500. There is some impact
outside the ux500 machine, but most of it is dealt with
in earlier patches.

It would be nicer to read the base addresses from DT properties and
convert the driver to use CLK_OF_DECLARE(), but this works too,
and it leaves the non-DT path alone for now.

This functionality will be used by the platform suspend operation also
which I am currently working on. So I would prefer if you can move it to
a separate file instead so it can be used by suspend as well. I
recommend to have it the same way we have it in our internal track i.e.
a file called pm.c in the machine.

While this is certainly the least invasive way to get rid of _PRCMU_BASE,
it sucks to refer to local variables in macros. How hard would it
be to find all users of these macros and put the prcmu_base addition
there?
The rest of this patch looks fine to me.

I would suggest splitting this change out into a separate patch, or
folding it into the one that creates the ux500.S file.

Did you forget to pass '-M' to git-format-patch?
You can set 'git config diff.renames true' to get this right in the future.

Was this meant to have been in a different patch? I don't see what it does here.

That would be nice to move this driver to drivers/cpuidle.
If you are ok with that, I can take care of moving the driver to this
directory and then create the pm.c file in the mach-ux500 to move the
prcmu specific code inside. Meanwhile this patch can be merged to group
the prcmu code needed for the driver and can be easily identified.

Until the clk-prmcu type gets split into register clocks and mailbox
clocks this patch work very fine!

That's probably a good enough reason to leave it alone for now, but we
should remember to fix it up later.
How about adding a comment in the header so we don't forget about it?

I'll prefer to have same way to access all PRCM registers.
prcmu_base should be used only in db8500-prcmu.c file and
db8500-prcmu-regs.h should contain register offset.
Register should be accessed in db8500-prcmu.c file like:
val = readl(prcmu_base + PRCM_XXX);
Linus, I'll propose you a patch derived from prcmu refactoring stuff.

Hi Linus,
Your patches from this morning made me curious about how much is still
missing to actually enable multiplatform support on ux500. This is
what I came up with, on top of your patches. Feel free to take what
you need if you don't already have the same patches.
I've successfully built "allmodconfig" with all the other v6/v7
platforms enabled as well.
Arnd

This header file only contains platform data structure definitions,
so it's straightforward to move.

This untangles the final bits of the prcmu code from the platform
code:
* The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c
because they are only of local significance.
* u8500_thsens_device goes into the prcmu, because it uses a PRCMU
IRQ that the platform does not see.
* IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data
because the PRCMU does not see it.

With the PRCMU out of the way, nothing outside of mach-ux500

A number of ux500 specific drivers include mach/hardware.h

To: linux-arm-kernel
There is only one instance of the platform data for synaptics_i2c_rmi4
in the mainline kernel, so there is no point of pretending its
variable here. The only member that has a dependency on the platform
is actually the interrupt number, and there is a field in the
i2c_client structure that gets initialized from the board info,
so we can trivially move the board_into into the platform without
knowledge of the platform_data structure.

These got missed in the treewide changes because they came in through
a new branch, and it now breaks allmodconfig builds.

mach/setup.h and mach/devices.h are only needed from inside of mach-ux500
now, so we can simply move them out of the include/mach directory.

Nothing is holding us up any more, and we can make ux500 coexist
with the rest of the platforms. The timex.h and uncompress.h
headers are no longer needed now.

If we try to build this file in a multiplatform configuration with
ARMv6 enabled, gas complains about the dsb operation being undefined.
Adding -march=armv7-a is safe because that code is only ever run
on ux500, which is Cortex-A9.

Unfortunately the platform stops booting after
2/9 "ARM: ux500: split out prcmu initialization"
so I will look closer at this.
This patch:
"ARM: ux500: kill mach/hardware.h some more"
I will squash into the actual removal patch, it's just
some sloppy work by me :-/
I will try to move some of the patches to the
front of the series so we only have the tricky stuff to
fix.
And there are some non-bisectable patches due to the
driver in staging (which was put there because Synaptics would
submit another driver "real soon now" and that was something like
two years ago), so I might have to squash some of them together to one.
Thanks!

Yes, I can see how it has potential for introducing bugs. I hope it's
something obvious that you can find easily.

What breaks bisection here? The "[PATCH 5/9] staging: ste_rmi4: kill
platform_data hack" patch should be independent of everything else,
it just touches more files than we'd like.

It includes <mach/irqs.h> that is removed by earlier patches, so
it stops compiling before this patch.

Ah right. I think I reordered the patches in the end and must have gotten

It appears that Lars-Peter Clausen sent a similar patch a bit earlier. I
added Arnd's Signed-off-by to give a credit, though. So, it is in
battery-urgent now.

If you write a patch like that it needs to go with this patch series
because I need this split out of the PRCMU driver to be able to
move forward with multiplatform.
I tried figuring out if I could just make this split as part of my
patch series which is simpler (then we just merge that into
ARM SoC and you can base CPUidle movement on that).
But then I get into the dilemma of where to put the header
file for these PM functions.
The goal of this series does away with <mach/*> so it can not be
any new <mach/pm.h> header.
The code will need to be called by idle code in drivers/cpuidle
and suspend code in mach-ux500. (Unless suspend/resume shall
also be moved to drivers/cpuidle? I guess not?)
Shall I put it in <linux/platform_data/arm-ux500-pm.h> or so,
with the implementation in arch/arm/mach-ux500/pm.c
or so?

Actually, I considered to move the driver to the right place as an
answer to Rickard who suggested to create the pm file.
As he is ok with that, I am ok with your patch splitting the prcmu code
and moving the code inside the cpuidle driver.
I proposed to take care of moving the prcmu code which falls in
cpuidle.c to a pm.c and then move the cpuidle.c file in driver/cpuidle
after your patch is applied.

No, it shouldn't :)

Wouldn't <asm/pm.h> be better ? So we can have the same header name for
all the drivers, no ?

I don't think that works with multiplatform. When building multiple
systems our approach is to not let any two header files have the same
name.
What we did for debug macro for example was to create the <debug/*>
namespace, so the old <mach/debug-macro.S> is now <debug/imx.S>,
<debug/vt8500.h>, <debug/ux500.h> ... etc.
So what would be needed would then rather be <pm/*> in
arch/arm/include/pm and under this we would create
<pm/ux500.h>.
But that require Russell and Arnds/Olofs consent I think,
what do you guys say? Other recommendations?

I would first like to understand what contents you actually need to
have in the header file.

So in this case headers for the PRCMU+GIC code moving out
of the PRCMU driver. These are the functions and the comments
right above them:
/* This function decouple the gic from the prcmu */
prcmu_gic_decouple()
/* This function recouple the gic with the prcmu */
prcmu_gic_recouple()
/*
* This function checks if there are pending irq on the gic. It only
* makes sense if the gic has been decoupled before with the
* db8500_prcmu_gic_decouple function. Disabling an interrupt only
* disables the forwarding of the interrupt to any CPU interface. It
* does not prevent the interrupt from changing state, for example
* becoming pending, or active and pending if it is already
* active. Hence, we have to check the interrupt is pending *and* is
* active.
*/
prcmu_gic_pending_irq()
/*
* This function checks if there are pending interrupt on the
* prcmu which has been delegated to monitor the irqs with the
* db8500_prcmu_copy_gic_settings function.
*/
bool prcmu_pending_irq()
/*
* This function checks if the specified cpu is in in WFI. It's usage
* makes sense only if the gic is decoupled with the db8500_prcmu_gic_decouple
* function. Of course passing smp_processor_id() to this function will
* always return false...
*/
bool prcmu_is_cpu_in_wfi()
/*
* This function copies the gic SPI settings to the prcmu in order to
* monitor them and abort/finish the retention/off sequence or state.
*/
int prcmu_copy_gic_settings()
This set of functions are called both for idling and suspend, i.e.
both by the machine-specific cpuidle driver and the machine-specific
suspend code.
They are conceptually coherent functions but messing with both PRCMU
and GIC registers, moving the responsibility of keeping track of the
IRQs back and forth between the GIC and the PRCMU.
Being able to freeze and decouple the GIC and check if a CPU is
in WFI is a ux500-PRCMU-specific pecularity but saves us a lot of
criss-cross IPIs when going to idle or sleep.

I still don't understand. From what I can tell, all those functions are
now statically declared in the cpuidle driver after your patch, so it
sounds like you do not need a header file for them any more, where
you needed one before. Which of those would you declare in a hypothetical
linux/pm/ux500.h header file?

So the issue raised by Rickard was that his suspend code (which
was just yesterday posted to linux-pm) is making use of the same
functions, so they need to be shared somehow.
Reference:
http://marc.info/?l=linux-pm&m=136397049416914&w=2
You find that this uses the affected funtions.
So they are not only for idling, and there are pending
patches for suspend making use of them, and suspend
needs to live in the machine.
