Jordan Crouse 9325d4266a drm/msm/gpu: Attach to the GPU GX power domain ... 99.999% of the time during normal operation the GMU is responsible for power and clock control on the GX domain and the CPU remains blissfully unaware. However, there is one situation where the CPU needs to get involved: The power sequencing rules dictate that the GX needs to be turned off before the CX so that the CX can be turned on before the GX during power up. During normal operation when the CPU is taking down the CX domain a stop command is sent to the GMU which turns off the GX domain and then the CPU handles the CX domain. But if the GMU happened to be unresponsive while the GX domain was left then the CPU will need to step in and turn off the GX domain before resetting the CX and rebooting the GMU. This unfortunately means that the CPU needs to be marginally aware of the GX domain even though it is expected to usually keep its hands off. To support this we create a semi-disabled GX power domain that does nothing to the hardware on power up but tries to shut it down normally on power down. In this method the reference counting is correct and we can step in with the pm_runtime_put() at the right time during the failure path. This patch sets up the connection to the GX power domain and does the magic to "enable" and disable it at the right points.
