We have a bug with omapdrm, where omapdrm calls dispc's pm_runtime function in atomic context, and dispc's pm_runtime is not marked as irq_safe: BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:952 Dispc's runtime PM callbacks are irq safe, so we can just set the irq_safe flag to fix the issue. However, in the long term, I'd rather have omapdrm manage the runtime PM calls in a better way. Calling get/put for every small operation that touches the dispc registers is very inefficient. It'd be better and cleaner to have clear "in-use" and "not-in-use" states for dispc, so that we don't need to do register context restore for small operations, only to turn dispc off right afterwards.
