[PATCH 1/7] media: vb2: add bidirectional flag in vb2_queue

2017-08-18 Thread Stanimir Varbanov
This change is intended to give to the v4l2 drivers a choice to change the default behavior of the v4l2-core DMA mapping direction from DMA_TO/FROM_DEVICE (depending on the buffer type CAPTURE or OUTPUT) to DMA_BIDIRECTIONAL during queue_init time. Initially the issue with DMA mapping direction
