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 series modifies the GPU GX domain on SDM845 to use a dummy enable function (leaving the GMU hardware to handle the power on) and the default disable function to allow the CPU to ensure that the power is off. With these changes we can attach the domain to the GMU device and control it from the start up and shut down functions as implemented by [2]. This patchset is based on the core GPU clock support from [1]. [1] https://patchwork.kernel.org/patch/10696671/ [2] https://patchwork.freedesktop.org/patch/262765/ v2: Rebase on the latest from Taniya and remove the GPU functions to make it easier to apply to the clock tree.
