[PATCH 1/3] DSS PM_WKEN to refill DMA

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Subramani Venkatesh <x0108988@xxxxxx>

Currently, DSS doesnot wakeup when there is a DMA request.
DSS wake up event must be enabled so that the DMA request to refill
the FIFO will wake up the CORE domain.
