Provide dt-schema documentation for Google gs101 SoC clock controller.
Currently this adds support for cmu_top, cmu_misc and cmu_apm.

I guess if William is using my script to build and flash the kernel it actually
runs the DTC checks as part of the build process.

See https://git.codelinaro.org/linaro/googlelt/pixelscripts/-/blob/clo/main/buildp21upstream.sh#L44

So it is a build test? We do not consider building as a test procedure,
otherwise I should add my and robots tested-by to many other patches.
Shall I consider other Tested-by tags here also as build-tested only?

Seems I missed the
"required:" go before "allOf:" comment here. Sorry about that I've fixed that
in v4.

Seems like a few other exynos clock yaml bindings need that fix to.

Ok just to be clear, are you saying I should have it like this?

  - if:
      properties:
        compatible:
          contains:
            enum:
              - google,gs101-cmu-misc
              - google,gs101-cmu-apm

    then:
      properties:
        clocks:
          minItems: 1
          items:
            - description: External reference clock (24.576 MHz)
            - description: Misc bus clock (from CMU_TOP)

        clock-names:
          minItems: 1
          items:
            - const: oscclk
            - const: dout_cmu_misc_bus

Instead of a dedicated  'if: const <compatible> then: ' for each CMU?

If I'm wrong above would you been kind enough to elaborate a bit
more on what you want, as all this dt-schema yaml stuff is a bit new
for me

Many thanks,

Peter

No, my bad, I meant apm + google,gs101-cmu-top

Ok so I should only add the Tested-by on the .c patches?

No. William indicated here

In my opinion, if someone performs only build testing, it is not a
testing. You cannot test the bindings other way than build testing, at
least I do not know such way. Of course other code like C or DTS affects
hardware so it can be tested.

What additional testing beside building and booting do you prefer at this
stage? I put my Tested-by for this patch because it includes the google,gs101.h
header which is used by the DT and clock controller driver during boot. Maybe
I should have been more clear on what I tested in each patch instead of only
mentioning how I tested in the cover letter?

Sorry for the confusion.

Thanks,
Will
