[PATCH 0/4] arm64: dts: ti: Cleanup mix of "okay" and "disabled" usage

[PATCH 0/4] arm64: dts: ti: Cleanup mix of "okay" and "disabled" usage

[Nishanth Menon]

Hi,

This is hopefully a conclusion of the thread we had (online[1] and
offline). There are few options one could take when dealing with SoC
dtsi and board dts:

a. SoC dtsi provide nodes as a super-set default (aka enabled) state and
   to prevent messy board files, when more boards are added per SoC, we
   optimize and disable commonly un-used nodes in board-common.dtsi
b. SoC dtsi disables all hardware dependent nodes by default and board
   dts files enable nodes based on a need basis.
c. Subjectively pick and choose which nodes we will disable by default
   in SoC dtsi and over the years we can optimize things and change
   default state depending on the need.

What we have today is a bit of a mix of seemingly random set of
choices, however, predominantly following (a) and a few intermittent
cases of (b) and (c). While there are pros and cons on each of these
approaches, the right thing to do will be to stick with device tree
default (aka device tree standards) and work within those established
rules. So, lets cleanup and follow what the vast majority of SoC
platforms are doing and which also happens to be the path of least churn
for TI dts nodes as well.

Functionally the dtb output is same ->
a) As of v5.10-rc1:
   am654: https://pastebin.ubuntu.com/p/G4P5vghpV3/
   j7200: https://pastebin.ubuntu.com/p/SsG6JtPzR9/
   j721e: https://pastebin.ubuntu.com/p/HWXmTwD6m8/

b) with this series applied:
   am654: https://pastebin.ubuntu.com/p/h7MmHPQpRx/
   j7200: https://pastebin.ubuntu.com/p/VXjQHhQNgn/
   j721e: https://pastebin.ubuntu.com/p/2JMgftd4Xx/

The actual diff between the two versions being: https://pastebin.ubuntu.com/p/4rwy5qRY84/
Which is equivalent as per device tree standards, but uses lesser
redundant strings.

Thanks Tony, for sticking to the guns and providing us clear guidance
on this topic.

[PATCH 1/4] arm64: dts: ti: k3-am65*: Cleanup disabled nodes at SoC dtsi level

[Nishanth Menon]

The device tree standard sets the default node behavior when status
property as enabled. There are many reasons for doing the same, number
of strings in device tree, default power management functionality etc
are few of the reasons.

In general, after a few rounds of discussions [1] there are few
options one could take when dealing with SoC dtsi and board dts

a. SoC dtsi provide nodes as a super-set default (aka enabled) state and
   to prevent messy board files, when more boards are added per SoC, we
   optimize and disable commonly un-used nodes in board-common.dtsi
b. SoC dtsi disables all hardware dependent nodes by default and board
   dts files enable nodes based on a need basis.
c. Subjectively pick and choose which nodes we will disable by default
   in SoC dtsi and over the years we can optimize things and change
   default state depending on the need.

While there are pros and cons on each of these approaches, the right
thing to do will be to stick with device tree default standards and
work within those established rules. So, we choose to go with option
(a).

Lets cleanup defaults of am654 SoC dtsi before this gets more harder
to cleanup later on and new SoCs are added.

The dtb generated is identical with the patch and it is just cleanup to
ensure we have a clean usage model

The only functional difference between the dtb generated is
status='okay' is no longer necessary for mcasp10 and depends on the
default state.

It should be:
When the status property is not present under a node, the "okay' value
is assumed.

Note: the device tree specification does not document default value as
such, see v0.3 (2.3.4, page 14).
Yes, the "okay" is used in case the status property is missing (by Linux
at least).

with expense of loc and readability.

Right, so how does that helps with devices present in the SoC, but no
node at all? First thing which comes to mind is AASRC, we don't have
Linux driver for it (and no DT binding document), but that does not mean
that it is not present. How PM would take that into account?

For the record: c was not really an option. There were no subjectivity,
the reason was pragmatic.

We are all familiar with the Devicetree specification, but let me quote
from chapter 2.3.4:
"okay"
Indicates the device is operational.

"disabled"
Indicates that the device is not presently operational, but it might
become operational in the future (for example, something is not plugged
in, or switched off).
Refer to the device binding for details on what disabled means for a
given device.

The reason why we kept McASP nodes (and dss) disabled in the soc dtsi
file is that they are not operation in the form they present in there.
They _need_ additional properties to be operational and those properties
can only be added in the board dts file.

This is not remotely a subjective view, this is the opposite of
subjectivity.

As for things not owned by the OS we have the "reserved" status.

Looks much better in this way.
?

I always wondered what is _not_ used by the board...
But it is not really about that, we need to disable these nodes as they
are incomplete in dtsi, they are not operational...

Maybe the spec update needs a formal release? Kumar's patch is merged:
https://github.com/devicetree-org/devicetree-specification/pull/33

on that exact same section, which you can see
https://github.com/devicetree-org/devicetree-specification/blob/master/source/chapter2-devicetree-basics.rst

Brings it to sync to:
https://elinux.org/Device_Tree_Linux#status_property

The "readability" part is subjective a bit.. enabled and disabled both
have verbosity problem lets see how we can optimize as new boards come
in.

I think we are mixing topics here -> I was stating the motivation why
devicetree chose such as default. Do we have a suggestion to improve
the description in the commit?

I dont think we are changing anything in the output dtb files, we are
just leaving the defaults as dt defaults and set the disable state in
board dts OR common board dtsi.

the usage of McASP was'nt meant as (c).. it is (b). is there a better way
to describe this in a generic manner?

Which is correct usage. I think your point with wkup_uart should be set as
reserved? I might have missed doing that - am I correct?

I don't question the fact that 'okay' is the default status if it is not
explicitly present. There is no better default than that.

this is different, these patches just removing the "status = 'okay';"
lines where they are not needed and can be omitted to save few lines and
it does help on readablity.

Correct, the resulted dtb is identical. If the developer for upcoming
boards did check the schematics vs TRM vs dtsi and spot the things that
is not configured.
dtb check will complain when it is starting to check against the
documentation, but McASP is not yet converted to yaml and to be honest I
don't want to convert the current binding to be the binding. When it was
done it just moved pdata variables to DT and that was wrong.
This is off-topic a bit.

> we are

Yes, we leave the non working/configured node 'okay' in dtsi and expect
that the board file author will know which node must be disabled because
it is incomplete.

I had my saying on that ever since I have been taking care of audio on
TI SoCs ;)

I used similar analogy in a private thread around this, but imho it fits
the case neatly:
car == McASP

you don't put an 'okay' (as is ready, operational) stamp on the car in
the middle of the production line when the engine is not even installed.

Not sure, I'm 'whatever' after [1] makes it to mainline or next.

I'm fine whatever way we take, but I think it is up to you to make the
call as the maintainer of the TI dts files... ;)

If we take this road, than I'm okay with it, but I'm going to take
silent protest (not sending acked-by or revired-by).
That should not stop you doing what you believe is best for the future!

fwiw, McASP will have sane handling for the variations of 'okay':

^^ -> Alright, that is all we are trying to do here: defaults in the
SoC.dtsi and specific cleanups (firmware reserved / board unused
disables) be done in a common board.dtsi (for now, there is no such
specific need, I guess).

Yes - I understand(and empathise) the implicit omission error risk we
are incurring here. I will add that to the commit message as well.

Completely agree with you. we are just insisting that this be done in
either common board.dtsi OR board.dtsi where applicable.

I don't see the relationship between the series.. I think this series
brings no change in dtb, hence with OR without your driver cleanup
series, there is no practical regressions.

Yep - I have'nt seen a reason yet that must cause us to change from the
Device tree default approach in our debates.


As Tony already pointed out.. if we start seeing a lot more boards for
an SoC..
Instead of (reverse issue- where we have a lot of places where people are
doing "okay" problem):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=12afc0cf81210969756daecd7eb48b307f08faed

We should look at ways to consolidate in a common-board.dtsi

OK - thanks for your review and the discussions, always appreciate
getting our views out there.

if there are no other comments, I will try and post a v2 over the
weekend.

The default is what it is: default choice which suits most of the nodes.

If the node is not complete in it's present form then it is not in it's
default state. imho.

This series opens up the possibility of nodes leaking to dtb with known
broken state and the driver should have a better strategy than 'works by
luck' to handle it ;)

Imho 'disabled' is the default for nodes like McASP as it is:
"Indicates that the device is not presently operational, but it might
become operational in the future" (for example, needed properties added
to the node).

[PATCH 3/4] arm64: dts: ti: am65/j721e: Fix up un-necessary status set to "okay" for crypto

The default state of a device tree node is "okay". There is no specific
use of explicitly adding status = "okay" in the SoC dtsi.
