MSM8916 seems to reuse the same hardware as MSM8974 and friends (for
whom this binding document was created). Add a new compatible for it.

Ok, I should have read dt-bindigns before sending a comment. But this
commit doesn't explain, why do you need an extra compat string.

Hm, MSM8916 doesn't have a *K*PSS (Krait Processor SubSystem), it has an
*A*PSS (ARM Cortex – A53 SubSystem, or Application Processor SubSystem).

I think this should be either qcom,msm8916-apss-acc, or you just keep
the qcom,msm8916-acc we already use. I'm guessing ACC stands for
"Application Clock Controller", so it would be unique enough already.

There is actually a patch from Rayyan already with a R-b from Krzysztof.
Maybe you, or whoever is responsible, can pick it up?

You would think that, but actually it's still called KPSS internally..

I'm not opposed to this either

Looks like Sebastian Reichel and/or Ulf pick up power dt-bindings patches

Folks, please merge Ryan work instead... I keep carrying this patch for
half a year:

Best regards,
