Hi,
This series adds a dma_dir field to the vb2_queue structure in order to
store the DMA direction once for all in vb2_queue_init();
It also adds a new capture_dma_bidirectional flag to the vb2_queue
structure allowing the hardware to read from the CAPTURE buffer. This
flag is ignored for OUTPUT queues. This is used on ChromeOS by the
rockchip-vpu driver.
Changes since v1:
- Renamed use_dma_bidirectional field as capture_dma_bidirectional
- Added a VB2_DMA_DIR() macro
