Hi everybody,
Here's the second version of the fbdev FOURCC-based format configuration API.
Compared to the previous version, I've removed the FB_VMODE_FOURCC bit (FOURCC
mode is now selected by a grayscale value 1), reorganized the union in the
fb_var_screeninfo structure, and added a
This API will be used to support YUV frame buffer formats in a standard
way.
Last but not least, create a much needed fbdev API documentation and
document the format setting APIs.

This patch adds support for CMA to dma-mapping subsystem for ARM
