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. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (831 commits) [media] cx88: make core less verbose [media] em28xx: fix oops at em28xx_dvb_bus_ctrl() [media] s5c73m3: fix indentation of the help section in Kconfig [media] cx25821-alsa: get rid of a __must_check warning [media] cx25821-video: declare cx25821_vidioc_s_std as static [media] cx25821-video: remove maxw from cx25821_vidioc_try_fmt_vid_cap [media] r820t: Remove a warning for an unused value [media] dib0090: Fix a warning at dib0090_set_EFUSE [media] dib8000: fix a warning [media] dib8000: Fix sub-channel range [media] dib8000: store dtv_property_cache in a temp var [media] dib8000: warning fix: declare internal functions as static [media] r820t: quiet gcc warning on n_ring [media] r820t: memory leak in release() [media] r820t: precendence bug in r820t_xtal_check() [media] videodev2.h: Remove the unused old V4L1 buffer types [media] anysee: Grammar s/report the/report to/ [media] anysee: Initialize ret = 0 in anysee_frontend_attach() [media] media: videobuf2: fix the length check for mmap [media] em28xx: save isoc endpoint number for DVB only if endpoint has alt settings with xMaxPacketSize != 0 ...
