From c3353330508aee4390442df2d7f6ce0ef5006185 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin <agust@denx.de> Date: Fri, 17 Dec 2010 06:40:50 -0300 Subject: [PATCH] [media] media: fsl-viu: fix support for streaming with mmap method 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.
