Merge tag 'media/v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 - Added support for some new video formats
 - mn88473 DVB frontend driver got promoted from staging
 - several improvements at the VSP1 driver
 - several cleanups and improvements at the Media Controller
 - added Media Controller support to snd-usb-audio.  Currently, enabled
   only for au0828-based V4L2/DVB boards
 - Several improvements at nuvoton-cir: it now supports wake up codes
 - Add media controller support to em28xx and saa7134 drivers
 - coda driver now accepts NXP distributed firmware files
 - Some legacy SoC camera drivers will be moving to staging, as they're
   outdated and nobody so far is willing to fix and convert them to use
   the current media framework
 - As usual, lots of cleanups, improvements and new board additions.
