It got rejected for v3.13.. Things need to be 'fixed' imx_drm first,
before new features are added..
Here's the patchset i used for v3.12.x
https://github.com/RobertCNelson/armv7-multiplatform/tree/v3.12.x/patches/imx_video
however, the v3.13.x version has more fixes from freescale..
https://github.com/RobertCNelson/armv7-multiplatform/tree/v3.13.x/patches/imx_video_staging
(i need to review the schematic on 0005-*)..
