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.

 Which device is registered depends on the type argument. The following
 types exist:
 
-- ``VFL_TYPE_GRABBER``: ``/dev/videoX`` for video input/output devices
-- ``VFL_TYPE_VBI``: ``/dev/vbiX`` for vertical blank data (i.e. closed captions, teletext)
-- ``VFL_TYPE_RADIO``: ``/dev/radioX`` for radio tuners
-- ``VFL_TYPE_SDR``: ``/dev/swradioX`` for Software Defined Radio tuners
-- ``VFL_TYPE_TOUCH``: ``/dev/v4l-touchX`` for touch sensors

 The last argument gives you a certain amount of control over the device
 device node number used (i.e. the X in ``videoX``). Normally you will pass -1
