[PATCH v2 0/4] gpu: host1x: add runtime pm support
This patch-set series adds runtime pm support for host1x, gr2d & dc. It retains the current behaviour if CONFIG_PM_RUNTIME is not enabled. For host1x & gr2d, the clocks are now enabled in .probe and disabled on its exit. This is needed for correct init of hardware. Additionally for gr2d, the clocks are also enabled when a new work is submitted and disabled when the work is done. Due to parent->child relations between host1x->gr2d, this scheme also ends up in enabling & disabling host1x clock For dc, the clocks are enabled in .probe and disabled in .remove but via runtime pm instead of direct clock APIs.
