Other drivers have therefore moved the pm_runtime calls out of spinlock context. For DSS, we have clk enable/disables around a set of register read/writes. This needs to be "relaxed". Idea is to add pm_runtime get/put sync calls near the user-space to kernel space entry points (syspend/resume, sysfs, ioctls) and remove the clk_enable/disable calls within the spinlock/unlocks in numerous functions.||Sumit, Mayuresh	+	| PM (OMAP2/3/4)||pm_runtime support||2.6.40 -> 3.1||Patches for DSS are ready (v2 posted on lo).
