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outdated and nobody so far is willing to fix and convert them to use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.
