[PATCH 0/7] drm/vc4: Fixup DT and DT binding issues from recent patchset

[PATCH 0/7] drm/vc4: Fixup DT and DT binding issues from recent patchset

[Dave Stevenson]

I missed the DT errors from the recent patchset[1] (DT patches
in linux-next via Florian, DRM bindings patches on dri-misc-next)
as Rob's bot report got spam filtered, so this is a fixup set.

Largely it was changes to number of interrupts or clocks in the
bindings, so those are now covered.

I've fixed up the missing "interrupt-controller" flags for 2711
and 2712 whilst here.

I can't get my head around what is meant to happen with ranges:
"soc@107c000000: firmware: 'ranges' is a required property"
The meaning seems obvious.

However if I add it then I get:
"firmware: '#address-cells', '#size-cells', 'dma-ranges', 'ranges' do
not match any of the regexes: 'pinctrl-[0-9]+'
from schema $id: http://devicetree.org/schemas/arm/bcm/raspberrypi,bcm2835-firmware.yaml#

There's obviously some other flag I need to set in the bindings,
but I can't work it out. We have similar errors for all the Pi
platforms for one or more nodes.
Please advise and I'll happily fix them all.

Thanks
  Dave

[PATCH 2/7] dtbindings: display: Fix BCM2835 HVS bindings for BCM2712

[Dave Stevenson]

The previous patch adding the compatible string missed out that
the number of interrupts and clocks changed with BCM2712 too.

Update to validate clock and interrupts for the variants.

There is no such commit in linux-next. Fix patches while they are on the
mailing list. If you refer here to broken DRM process, then basically
you are on your own because we won't able to see it.

Typo in subject prefix. It's dt-bindings.

Do not mix cleanups with bugfixes.

BTW, do not mix DTS to DRM. DRM has its own development style. DTS
*cannot* be merged there, so combining these series is not welcomed and
leads to issues (like DRM applying DTS!).

No one uses term like "dtbinding". Use full make target name or DT schema.

But are these valid? Why do you think that binding is correct? Or you
just silence the warning regardless whether this matches the hardware?

Which issues? Be specific. Such commit is unprecise and not really
helpful. We see it from the diff that this is "some issue". What we do
not see is WHY and WHAT the ISSUE is.

Nothing in the DTS patches suggested targeting DRM, so this patchset is
organized in pretty surprising way. Please split them per subsystem. DTS
is never for driver subsystem.

Subject: drop full stop.

No address space here, so why ranges?

Did you actually test these changes, because the last time [1] it broke
the boot of RPi 4 and likely for RPi 5, too?

Sorry for the nitpicking, but gpiolib is a software part of Linux and we

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:
./Documentation/devicetree/bindings/display/brcm,bcm2711-hdmi.yaml:59:9: [warning] wrong indentation: expected 10 but found 8 (indentation)

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20241202-dt-bcm2712-fixes-v1-1-fac67cc2f98a@raspberrypi.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

That is not what was done, I took the DTS patches via the Broadcom ARM 
SoC tree, as I usually do, unless someone tells me otherwise.

We got a number of DTS warnings after I took Dave's patches so I asked 
for those to be fixed, as it turns out there are binding and DTS fixes.

I intend to squash these fixes with their original commit, so all of 
those commit messages will be discarded, they are only meant to be 
transitional.

A link to the robot email would have probably been helpful in 
understanding which dt checker errors are being fixed here. Regardless, 
as indicated in patch #4, those commit messages will be discarded since 
I intend to fixup the original commits directly into my tree I would not 
put too much effort into addressing any comments there, unless there is 
some piece of information that should have been provided in the original 
commit, in which case I can squash, rather than fixup.
