Merge tag 'media/v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- New sensor driver: ov5693
- A new driver for STM32 Chrom-ART Accelerator
- Added V4L2 core helper functions for VP9 codec
- Hantro driver has gained support for VP9 codecs
- Added support for Maxim MAX96712 Quad GMSL2 Deserializer
- The staging atomisp driver has gained lots of improvements, fixes and
cleanups. It now works with userptr
- Lots of random driver improvements as usual
