[Freedreno] [RFC 0/4] msm: clk: Define a special power domain for SDM845 GX

[Jordan Crouse]

The GPU GX domain on SDM845 is nominally managed by the GMU microcontroller
but there are certain circumstances when the CPU needs to be sure that the
GX headswitch is off.

This RFC series adds a special modification for the GX power domain
that always returns success for domain power on and uses the default
gdsc functions for power down.

With this, we should be able to remove most of GX clocks from the gpucc
and have a relatively clean way of handling the hardware workaround.

This is based on the series from [1] with some slight changes for the
current for-next from Andy.
