[PATCH v4 0/3] fbdev: Add FOURCC-based format configuration API

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

Hi everybody,

Here's the fourth version of the fbdev FOURCC-based format configuration API.

The third version nearly got merged, but we noticed that gcc choked on
anonymous union initializers. This has been fixed in gcc 4.6, but I don't have
the power to force Linux to set the base gcc version to 4.6 :-)

There were two ways to fix the issue, neither of which was particularly
attractive to me. The first one involved a 10k lines patch that modified all
the drivers, and the second one required using one of the reserved fields in
the fb_var_screeninfo structure. After discussing this with Florian, I've
decided to go for the second fix.

The colorspace field is thus now stored in a previously reserved field. The
fourcc field is still shared with the grayscale field, but doesn't have its
own name anymore.

I've updated the fbdev-test tool to this new API. The code is available in the
fbdev-test yuv branch at
http://git.ideasonboard.org/?pûdev-test.git;a=shortlog;h=refs/heads/yuv.
