Merge tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

 - new Intel IVSC MEI drivers

 - some Mediatek platform drivers were moved to a common location

 - Intel atomisp2 driver is now working with the main ov2680 driver. Due
   to that, the atomisp2 ov2680 staging one was removed

 - the bttv driver was finally converted to videobuf2 framework. This
   was the last one upstream using videobuf version 1 core. We'll likely
   remove the old videobuf framework on 6.7

 - lots of improvements at atomisp driver: it now works with normal I2C
   sensors. Several compile-mode dependecies to select between ISP2400
   and ISP2401 are now solved in runtime

 - a new ipu-bridge logic was added to work with IVSC MEI drivers

 - venus driver gained better support for new VPU versions

 - the v4l core async framework has gained lots of improvements and
   cleanups

 - lots of other cleanups, improvements and driver fixes
