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.
