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 * tag 'media/v6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (358 commits) media: ivsc: Add ACPI dependency media: bttv: convert to vb2 media: bttv: use audio defaults for winfast2000 media: bttv: refactor bttv_set_dma() media: bttv: move vbi_skip/vbi_count out of buffer media: bttv: remove crop info from bttv_buffer media: bttv: remove tvnorm field from bttv_buffer media: bttv: remove format field from bttv_buffer media: bttv: move do_crop flag out of bttv_fh media: bttv: copy vbi_fmt from bttv_fh media: bttv: copy vid fmt/width/height from fh media: bttv: radio use v4l2_fh instead of bttv_fh media: bttv: replace BUG with WARN_ON media: bttv: use video_drvdata to get bttv media: i2c: rdacm21: Fix uninitialized value media: coda: Remove duplicated include media: vivid: fix the racy dev->radio_tx_rds_owner media: i2c: ccs: Check rules is non-NULL media: i2c: ds90ub960: Fix PLL config for 1200 MHz CSI rate media: i2c: ds90ub953: Fix use of uninitialized variables ...

+description:
+ An I2C Address Translator (ATR) is a device with an I2C slave parent
+ ("upstream") port and N I2C master child ("downstream") ports, and
+ forwards transactions from upstream to the appropriate downstream port
+ with a modified slave address. The address used on the parent bus is
+ called the "alias" and is (potentially) different from the physical
+ slave address of the child bus. Address translation is done by the
+ hardware.

+ description:
+ I2C alias pool is a pool of I2C addresses on the main I2C bus that can be
+ used to access the remote peripherals on the serializer's I2C bus. The
+ addresses must be available, not used by any other peripheral. Each
+ remote peripheral is assigned an alias from the pool, and transactions to
+ that address will be forwarded to the remote peripheral, with the address
+ translated to the remote peripheral's real address. This property is not
+ needed if there are no I2C addressable remote peripherals.
