This is a Display PWM, not a generic PWM.

My comment about pwm schema was ignored.

Please include pwm.yaml.

Need a const. Description can be skipped, it's obvious.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

mt8183 was not in the original text file binding. Please split this out.
Also, the combination "mediatek,mt8167-disp-pwm", "mediatek,mt8173-disp-pwm"
is missing.

Yes, you should add it in another patch, not in the conversion patch.

It was in the original binding, so yes you need to preserve it when you
convert the binding. Otherwise you would have changed things when doing
the conversion.

The driver doesn't have it because it is falling back to the mt8173 one.

It seems unlikely that every SoC has a different version of h/w for 
something as simple as a PWM. There's not an appropriate fallback? The 
first version from an SoC that has all the features and would work with 
existing driver unchanged?

Using Documentation/devicetree/bindings/mmc/mtk-sd.yaml as a reference,
you would have:
  compatible:
    oneOf:
      - enum:
        - mediatek,mt6595-disp-pwm
        - mediatek,mt8173-disp-pwm
        - mediatek,mt8183-disp-pwm
      - items:
        - const: mediatek,mt8186-disp-pwm
        - const: mediatek,mt8183-disp-pwm
      ...

Why did you drop [PATCH] tag in the subject of your patch series?
Please keep it for distinguishing it from RFC/RESEND and other 
meaningful tags next time.

Thanks

I also asked for this in v1 patchset, so it's a pity my suggestion was
not listened to.

Any reason in changing your email address in all patches? Maybe some
mail client misconfiguration?
