Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media update from Mauro Carvalho Chehab:
- OF documentation and patches at core and drivers, to be used by for
embedded media systems
- some I2C drivers used on go7007 were rewritten/promoted from staging:
sony-btf-mpx, tw2804, tw9903, tw9906, wis-ov7640, wis-uda1342
- add fimc-is driver (Exynos)
- add a new radio driver: radio-si476x
- add a two new tuners: r820t and tuner_it913x
- split camera code on em28xx driver and add more models
- the cypress firmware load is used outside dvb usb drivers. So, move
it to a common directory to make easier to re-use it
- siano media driver updated to work with sms2270 devices
- several work done in order to promote go7007 and solo6x1x out of
staging (still, there are some pending issues)
- several API compliance fixes at v4l2 drivers that don't behave as
expected
- as usual, lots of driver fixes, improvements, cleanups and new device
addition at the existing drivers.
