[PATCH 0/9] dt-bindings: PCI: qcom: Add missing required power-domains

[PATCH 0/9] dt-bindings: PCI: qcom: Add missing required power-domains

[Krzysztof Kozlowski]

Recent binding changes forgot to make power-domains required.

I am not updating SC8180xp because it will be fixed other way in my next
patchset.

Best regards,
Krzysztof

I have a feeling I've pointed this out before, but these kind of binding
patches really does not seem to qualify for stable backporting (e.g.
does not "fix a real bug that bothers people").

I wish stable users of DT bindings (so some 3rd party projects or
product trees) keep testing their stable kernels, their stable DTS with
the bindings, whenever they upgrade their LTS kernel. And if they keep
testing then they should be told about lack of the power domain. That's
why this is for.

Of course fix impact is pretty small, so I don't mind if the stable tag
is being dropped here, but I will not resend just for that unless PCI or
stable maintainers ask me.

Best regards,
Krzysztof

I am going through more of the bindings and I noticed now that "resets"
also were within "if:not:" and they should be required here too.

All patchses will be fixed in v2.

Presumably if someone omits power-domain and the driver doesn't work, 
then it's a bug affecting them.

I'm fine with dropping the stable tag because it will still most likely 
get picked up with the Fixes tag. :)

Yeah, and any such devicetree source fix would be a candidate for stable
backporting.

Heh. I skimmed the 6.16 stable branch and it seems it was mostly
explicitly tagged binding patches that ended up being backported.
