Merge tag 'media/v5.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - dvb-usb drivers entries got reworked to avoid usage of magic numbers
   to refer to data position inside tables

 - vcodec driver has gained support for MT8186 and for vp8 and vp9
   stateless codecs

 - hantro has gained support for Hantro G1 on RK366x

 - Added more h264 levels on coda960

 - ccs gained support for MIPI CSI-2 28 bits per pixel raw data type

 - venus driver gained support for Qualcomm custom compressed pixel
   formats

 - lots of driver fixes and updates
