This patch set is introduced to support a driver we are developing
for our new Video Framebuffer DMA IP, a DMA device that is "video format aware".
Clients need only specify memory layout information for a single plane
(i.e. luma) and then provide a video format code (e.g. YUV420) which will permit
for intelligent reads or writes (depending on the IP configuration) to host
memory with only a minimal set of video memory configuration data.
The IP supports a variety of 8-bit and 10-bit video formats, some of which
are not represented in the current V4L2 user api or framework. This patch
set introduces these needed video format codes and updates the
framework with the metadata required.
The DMA driver requiring these updates is not being submitted as part of this
patch set as it is still undergoing final development.
We are submitting this patch series for review and comment with regard to
ensuring we haven't missed any required framework updates and/or in regards to
the choices we've made to the fourcc string values.
