Merge tag 'media/v6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- DVB budget legacy API was finally documented. It took only 20+ years
to get some documentation about it...
- hantro driver has gained support for STM32MP25 VDEC/VENC
- rkisp1 has gained support for i.MX8MP
- atomisp got rid of two items from its todo list. Still 5 items
pending for moving it out of staging
- lots of driver fixes, cleanups and improvements
