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 use_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.
