This series adds a new SA8540P GPU clock controller compatible which can be used to determine whether to look up the external supply. This specifically avoids warnings such as: gpu_cc-sc8280xp 3d90000.clock-controller: supply vdd-gfx not found, using dummy regulator on SC8280XP, which were introduced in 6.9-rc1. Note that this also avoids triggering a potential deadlock on SC8280XP even if the underlying issue still remains for the derivative platforms like SA8540P and SA8295P that actually use the supply. [1] Also note that this is a better alternative to simply making the external supply optional as that would suppress any warnings about missing supplies on platforms that actually require it. This series therefore supersedes [2].
