[Intel-gfx] [PATCH v8 7/7] drm/i915/mtl: Add support for PM DEMAND

[Govindapillai, Vinod]

Thanks for the reviews and comments

I still think port_clock changes should catch any active phys changes.

IMO, this is being going on for a while and could be optimized later as well if needed!

But lets see if someone can comment on that.

Btw, sorry about the screw up with my previous replay formats - was using phone!!
