Merge tag 'media/v6.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- v4l core: subdev frame interval now supports which field
- v4l kapi: moves and renames the init_cfg pad op to init_state as an
internal op.
- new sensor drivers: gc0308, gc2145, Avnet Alvium, ov64a40, tw9900
- new camera driver: STM32 DCMIPP
- s5p-mfc has gained MFC v12 support
- new ISP driver added to staging: Starfive
- new stateful encoder/decoded: Wave5 codec It is found on the J721S2
SoC, JH7100 SoC, ssd202d SoC. Etc.
- fwnode gained support for MIPI "DisCo for Imaging"
(https://www.mipi.org/specifications/mipi-disco-imaging)
- as usual, lots of cleanups, fixups and driver improvements.
