This is not a valid path. Please correct it, otherwise tools cannot
validate it.

I don't know what and why happened here. I asked for different order of
properties and properties are gone. Provide detailed changelog.

So no schema? Sorry, this is very confusing.

I am not going to review the rest. You implemented some odd changes, not
what was asked. At least not entirely. With no changelog explaining
this, you basically expect me to do review from scratch like there was
no previous review.

That's not how it works.

Best regards,
Krzysztof

Somehow got this weird idea out of qcom,msm8953.yaml

seems its wrong over there too.

Should proper line be like? :
  See also:: include/dt-bindings/interconnect/qcom,msm8976.h

For disappearing props it turns out clocks which i had defined for it
aren't required so these were wiped from yaml+driver.

As both yamls will not differ much from qcom,msm8939.yaml 
i moved compatibles in it for v3.

Would be great to discuss it before resending on #linux-msm
