Merge tag 'media/v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Documentation for digital TV (both kAPI and uAPI) are now in sync
with the implementation (except for legacy/deprecated ioctls). This
is a major step, as there were always a gap there
- New sensor driver: imx274
- New cec driver: cec-gpio
- New platform driver for rockship rga and tegra CEC
- New RC driver: tango-ir
- Several cleanups at atomisp driver
- Core improvements for RC, CEC, V4L2 async probing support and DVB
- Lots of drivers cleanup, fixes and improvements.
