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
