Changes compared to v3: 1. Rebased on top of Jonathan's patch which adds support for changing gpu freq through hfi on newer targets. Created patch 1 to make this the generic approach of setting gpu freq on newer targets. 2. As suggested by Rob, left the icc_path intact for pre-a6xx GPUs. As mentioned in [1], these patches have dependency on Georgi's series from opp/linux-next [2] and also Sibi's patch which adds a helper function to set and clear ddr bandwidth vote [2].
