[PATCH RFT 0/5] drm/msm: Attach a driver to GMU

[Akhil P Oommen]

With the introduction of sync_state in the genpd framework, any consumer
device of GCC and GPUCC which is not bound to a driver will result in
bootup warnings like below:

[   24.362666] gcc-kaanapali 100000.clock-controller: sync_state() pending due to 3d37000.gmu
[   24.371210] gxclkctl-kaanapali 3d64000.clock-controller: sync_state() pending due to 3d37000.gmu
[   24.380268] gpucc-kaanapali 3d90000.clock-controller: sync_state() pending due to 3d37000.gmu

To silence these warnings and also to have a proper state in driver core,
attach a driver to the GMU and set it up as a component device for the drm
master device.

The first few patches are preparatory fixes and refactorings. And the
final patch introduces a driver for GMU devices.
