Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"This series contain:
- new i2c video drivers: ml86v7667 (video decoder),
ths8200 (video encoder)
- a new video driver for EasyCap cards based on Fushicai USBTV007
- Improved support for OF and embedded systems, with V4L2 async
initialization and a better support for clocks
- API cleanups on the ioctls used by the v4l2 debug tool
- Lots of cleanups
- As usual, several driver improvements and new cards additions
- Revert two changesets that change the minimal symbol rate for
stv0399, as request by Manu
- Update MAINTAINERS and other files to point to my new e-mail"
