Re: [PATCH] arm64: dts: qcom: x1e80100: Add GFX power domain to GPU clock controller

According to documentation, the VDD_GFX is powering up the whole GPU subsystem. The VDD_GFX is routed through the RPMh GFX power domain.

So tie the RPMh GFX power domain to the GPU clock controller.

You shouldn't be messing with VDD_GFX on platforms with a GMU.

Parts of the clock controller are backed by one of the MX rails, with some logic depending on CX/GFX, but handling of the latter is fully deferred to the GMU firmware.
