Changes v1->v2:
* added commit message (not just the subject)

NOTE motivation for this is that some not yet mainlined DTS already use
both:

https://github.com/sdm660-mainline/linux/blob/sdm660-next-stable/arch/arm64/boot/dts/qcom/sdm636-asus-x00td.dts

Kind regards,

I'd expect the GPU clock controller to be a module, can you please
clarify why it needs to be builtin?

To allow the display to be enabled early enough?
That sounds like a terrible bug in drm/msm.. Display should
be wholly separate from Adreno.
