Merge tag 'media/v6.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - the old V4L2 core videobuf kAPI was finally removed. All media
   drivers should now be using VB2 kAPI

 - new automotive driver: mgb4

 - new platform video driver: npcm-video

 - new sensor driver: mt9m114

 - new TI driver used in conjunction with Cadence CSI2RX IP to bridge
   TI-specific parts

 - ir-rx51 was removed and the N900 DT binding was moved to the
   pwm-ir-tx generic driver

 - drop atomisp-specific ov5693, using the upstream driver instead

 - the camss driver has gained RDI3 support for VFE 17x

 - the atomisp driver now detects ISP2400 or ISP2401 at run time. No
   need to set it up at build time anymore

 - lots of driver fixes, cleanups and improvements
