Merge tag 'media/v5.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- New sensor driver: imx219
- Support for some new pixelformats
- Support for Sun8i SoC
- Added more codecs to meson vdec driver
- Prepare for removing the legacy usbvision driver by moving it to
staging. This driver has issues and use legacy core APIs. If nobody
steps up to address those, it is time for its retirement.
- Several cleanups and improvements on drivers, with the addition of
new supported boards
