Merge tag 'media/v4.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- videobuf2 was moved to a media/common dir, as it is now used by the
DVB subsystem too
- Digital TV core memory mapped support interface
- new sensor driver: ov7740
- several improvements at ddbridge driver
- new V4L2 driver: IPU3 CIO2 CSI-2 receiver unit, found on some Intel
SoCs
- new tuner driver: tda18250
- finally got rid of all LIRC staging drivers
- as we don't have old lirc drivers anymore, restruct the lirc device
code
- add support for UVC metadata
- add a new staging driver for NVIDIA Tegra Video Decoder Engine
- DVB kAPI headers moved to include/media
- synchronize the kAPI and uAPI for the DVB subsystem, removing the gap
for non-legacy APIs
- reduce the kAPI gap for V4L2
- lots of other driver enhancements, cleanups, etc.
