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: "The main set of series of patches for media subsystem, including: - document RC sysfs class - added an API to setup scancode to allow waking up systems using the Remote Controller - add API for SDR devices. Drivers are still on staging - some API improvements for getting EDID data from media inputs/outputs - new DVB frontend driver for drx-j (ATSC) - one driver (it913x/it9137) got removed, in favor of an improvement on another driver (af9035) - added a skeleton V4L2 PCI driver at documentation - added a dual flash driver (lm3646) - added a new IR driver (img-ir) - added an IR scancode decoder for the Sharp protocol - some improvements at the usbtv driver, to allow its core to be reused. - added a new SDR driver (rtl2832u_sdr) - added a new tuner driver (msi001) - several improvements at em28xx driver to fix PM support, device removal and to split the V4L2 specific bits into a separate sub-driver - one driver got converted to videobuf2 (s2255drv) - the e4000 tuner driver now follows an improved binding model - some fixes at V4L2 compat32 code - several fixes and enhancements at videobuf2 code - some cleanups at V4L2 API documentation - usual driver enhancements, new board additions and misc fixups" [ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce indentation in of_graph_get_next_endpoint"). The of_graph_get_next_endpoint() function was moved and renamed by commit fd9fdb78a9bf ("[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of"). It was originally called v4l2_of_get_next_endpoint() and lived in the file drivers/media/v4l2-core/v4l2-of.c. In that original location, it was then fixed to support empty port nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port nodes"), and that commit clashes badly with the dropped "Reduce intendation" commit. I had to choose one or the other, and decided that the "Support empty port nodes" commit was more important ] * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (426 commits) [media] em28xx-dvb: fix PCTV 461e tuner I2C binding Revert "[media] em28xx-dvb: fix PCTV 461e tuner I2C binding" [media] em28xx: fix PCTV 290e LNA oops [media] em28xx-dvb: fix PCTV 461e tuner I2C binding [media] m88ds3103: fix bug on .set_tone() [media] saa7134: fix WARN_ON during resume [media] v4l2-dv-timings: add module name, description, license [media] videodev2.h: add parenthesis around macro arguments [media] saa6752hs: depends on CRC32 [media] si4713: fix Kconfig dependencies [media] Sensoray 2255 uses videobuf2 [media] adv7180: free an interrupt on failure paths in init_device() [media] e4000: make VIDEO_V4L2 dependency optional [media] af9033: Don't export functions for the hardware filter [media] af9035: use af9033 PID filters [media] af9033: implement PID filter [media] rtl2832_sdr: do not use dynamic stack allocation [media] e4000: fix 32-bit build error [media] em28xx-audio: make sure audio is unmuted on open() [media] DocBook media: v4l2_format_sdr was renamed to v4l2_sdr_format ...
