Merge tag 'media/v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 "Media updates for v4.12-rc1:

   - new driver to support mediatek jpeg in hardware codec

   - rc-lirc, s5p-cec and st-cec staging drivers got promoted

   - hardware histogram support for vsp1 driver

   - added Virtual Media Controller driver, to make easier to test the
     media controller

   - added a new CEC driver (rainshadow-cec)

   - removed two staging LIRC drivers for obscure hardware that are too
     obsolete

   - added support for Intel SR300 Depth camera

   - some improvements at CEC and RC core

   - lots of driver cleanups, improvements all over the tree

  With this series, we're finally getting rid of the LIRC staging
  driver. There's just one left (lirc_zilog), with require more care,
  as part of its functionality (IR RX) is already provided by another
  driver. Work in progress to convert it on the proper way"
