Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
"The main set of series of patches for media subsystem, including:
- document RC sysfs class
- added an API to setup scancode to allow waking up systems using the
Remote Controller
- add API for SDR devices. Drivers are still on staging
- some API improvements for getting EDID data from media
inputs/outputs
- new DVB frontend driver for drx-j (ATSC)
- one driver (it913x/it9137) got removed, in favor of an improvement
on another driver (af9035)
- added a skeleton V4L2 PCI driver at documentation
- added a dual flash driver (lm3646)
- added a new IR driver (img-ir)
- added an IR scancode decoder for the Sharp protocol
- some improvements at the usbtv driver, to allow its core to be
reused.
- added a new SDR driver (rtl2832u_sdr)
- added a new tuner driver (msi001)
- several improvements at em28xx driver to fix PM support, device
removal and to split the V4L2 specific bits into a separate
sub-driver
- one driver got converted to videobuf2 (s2255drv)
- the e4000 tuner driver now follows an improved binding model
- some fixes at V4L2 compat32 code
- several fixes and enhancements at videobuf2 code
- some cleanups at V4L2 API documentation
- usual driver enhancements, new board additions and misc fixups"
[ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce
indentation in of_graph_get_next_endpoint").
The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9bf ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]
