PM (OMAP2/3/4)pm_runtime support2.6.40The pm_runtime get/put_sync apis cannot be called from interrupt or spinlock context. 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".
