Upcoming features/patchsets

Feature Content Targeted kernel.org Release Status / Dependencies Owner
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". 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
