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.
