Merge tag 'media/v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - a new sensor driver for ov5675

 - a new platform driver for Allwinner A10 sensor interface

 - some new remote controller keymaps

 - some cosmetic changes at V4L2 core in order to avoid #ifdefs and to
   merge two core modules into one

 - removal of bcm2048 radio driver from staging

 - removal of davinci_vpfe video driver from staging

 - regression fix since Kernel 5.1 at the legacy VideoBuffer version 1
   core

 - added some documentation for remote controller protocols

 - pixel format documentation was split on two files

 - lots of other driver improvements and cleanups
