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
