  Add a compatible string for MediaTek Helio X10 MT6795's display PWM
block: this is the same as MT8173.

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.

These are not new warnings. I think we should address them in a different patch. 
In my opinion it shouldn't block this patch. In the end it only add as 
compatible here.

I agree. These warnings should not block this patch, as they're totally unrelated
to it.

I assume this patch will go in together with the other patches in this
series via an ARM tree? (I.e. not via pwm.)

This does not look correct. You do not add compatible, you replace
breaking all mt8167-disp-pwm. At least it looks like this from context.

I thought the old semantic to be:

	"mediatek,mt8167-disp-pwm"

and the new

	"mediatek,mt6795-disp-pwm" or "mediatek,mt8167-disp-pwm"

. What am I missing?

The new is ok for mt6795 but it is not valid for mt8167.

Sorry, why is it not valid for MT8167?

This is changing the doc from:

OLD:
       - items:
           - const: mediatek,mt8167-disp-pwm
           - const: mediatek,mt8173-disp-pwm
NEW:

       - items:
           - enum:
               - mediatek,mt6795-disp-pwm
               - mediatek,mt8167-disp-pwm
           - const: mediatek,mt8173-disp-pwm

For me, that's totally valid, as the old semantic was:

compatible = "mediatek,mt8167-disp-pwm", "mediatek,mt8173-disp-pwm";

...and the new semantic is .. the same; this commit only *adds* the
possibility to get a

compatible = "mediatek,mt6795-disp-pwm", "mediatek,mt8173-disp-pwm";

without breaking anything.

Angelo

Eh, above example did not help me, because it missed mt8173, but I see
now the context I missed. It's already a list of two compatibles, so the
patch is fine.

I disagree if it's the schema that needs fixing. From the looks of 
it, I'd say it's probably at least some schema fixes needed.

Are you saying the MT6795 has no power-domains?

The commit message says the MT6795 is the same as the MT8173. Which is

That's totally fine, I'll take this patch through my tree once everything is ready.
