Merge tag 'media/v6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - Lots of improvement at atomisp driver, which is starting to look in
   good shape

 - Mediatek vcodec driver has gained support for av1 and hevc stateless
   codecs

 - New sensor driver: ov01a10

 - verisilicon driver has gained AV1 entropy helpers

 - tegra-video has gained support for Tegra20 parallel input

 - dvb core has gained an extra property to better support DVB-S2X

 - as usual, lots of cleanups, fixes and improvements on media drivers
