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.
