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"
