V4L/DVB: V4L2: Add support for OMAP2/3 V4L2 display driver on top of DSS2
Features Supported - 1. Provides V4L2 user interface for the video pipelines of DSS 2. Basic streaming working on LCD, DVI and TV. 3. Works on latest DSS2 library from Tomi 4. Support for various pixel formats like YUV, UYVY, RGB32, RGB24, RGB565 5. Supports Alpha blending. 6. Supports Color keying both source and destination. 7. Supports rotation. 8. Supports cropping. 9. Supports Background color setting. 10. Allocated buffers to only needed size Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Reviewed-by: Hans Verkuil <hverkuil@xs4all.nl> Reviewed-by: Muralidharan Karicheri <mkaricheri@gmail.com> Signed-off-by: Murailidharan Karicheri <mkaricheri@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
