I was pretty sure that MPlayer supports 12bit greyscale, but I cannot
find where it was handled. You can of course pass it to the MPlayer
internas as 8bit greyscale, which would be IMGFMT_Y8 or just pass
it on as 16bit which would be IMGFMT_Y16_LE (LE = little endian).
You can find the internal #defines of the image formats in
libmpcodecs/img_format.h and can use https://www.fourcc.org/yuv.php
to decode their meaning.
The equivalent for libav would be libavutil/pixfmt.h
Luca Barbato tells me that adding Y12 support to libav would be easy.

This is from linux-next-2012-07-19 plus two patches from Shawn Guo:
[PATCH v2 1/2] clk: fix clk_get on of_clk_get_by_name return check
[PATCH v2 2/2] clk: fix compile for OF && !COMMON_CLK
Especialy the second one is needed to get the system booting.
Config is more or less mxs_defconfig, with a few additional drivers
enabled.

Hi, I'm working on an embedded system based on a Freescale ARM9 processor i.mx23. While trying linux-next i stumpled over my login prompt getting broken.

Do what anyone with a little bit of brain would do: publish it[1]!
Patenting it and using as defensive patent wont work. Unless
you are able to control Saurons Ring. If you want to know more
just read up on current patent practice. IEEE has quite a few
articles on that issue, i'm sure that ACM and the like should
have also a few.
