Subject: [media] media: fsl-viu: fix support for streaming with mmap method Author: Anatolij Gustschin <[email protected]> Date: Fri Dec 17 06:40:50 2010 -0300 Streaming using mmap didn't work in the VIU driver. We need to start/stop DMA in streamon/streamoff and free the buffers on release. Add appropriate driver extension now.
