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

Each of the subdevs provide a V4L2 subdev -interface to userspace. - - DAVINCI ISIF - DAVINCI IPIPEIF - DAVINCI IPIPE - DAVINCI CROP RESIZER - DAVINCI RESIZER A - DAVINCI RESIZER B - -Each possible link in the VPFE is modelled by a link in the Media controller -interface.
