Merge tag 'media/v6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- DVB core changes to avoid refcount troubles and UAF
- DVB API/core has gained support for DVB-C2 and DVB-S2X
- New sensor drivers: ov08x40, ov4689.c, st-vgxy61 and tc358746.c
- Removal of an unused sensor driver: s5k4ecgx
- Move microchip_csi2dc to a new directory, named after the
manufacturer
- Add media controller support to Microship drivers
- Old Atmel/Microship drivers that don't use media controler got moved
to staging
- New drivers added for Renesas RZ/G2L CRU and MIPI CSI-2 support
- Allwinner A31 camera sensor driver code was now split into a bridge
and a separate processor driver
- Added a virtual stateless decoder driver in order to test core
support for stateless drivers and test userspace apps using it
- removed platform-based support for ov9650, as this is not used
anymore
- atomisp now uses videobuf2 and supports normal mmap mode
- the imx7-media-csi driver got promoted from staging
- rcar-vin driver has gained support for gen3 UDS (Up Down Scaler)
- most i2c drivers now use I2C .probe_new() kAPI
- lots of drivers fixes, cleanups and improvements
