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 ...

i2c: Update documentation to use .probe() again

2023-08-14T16:14:04+00:00

Since commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") .probe() is the recommended callback to implement (again). Reflect this in the documentation and don't mention .probe_new() any more.

media: i2c: add I2C Address Translator (ATR) support

2023-07-14T11:11:44+00:00

An ATR is a device that looks similar to an i2c-mux: it has an I2C slave "upstream" port and N master "downstream" ports, and forwards transactions from upstream to the appropriate downstream port. But it is different in that the forwarded transaction has a different slave address. The address used on the upstream bus is called the "alias" and is (potentially) different from the physical slave address of the downstream chip. Add a helper file (just like i2c-mux.c for a mux or switch) to allow implementing ATR features in a device driver. The helper takes care of adapter creation/destruction and translates addresses at each transaction.

docs: i2c: slave-interface: return errno when handle I2C_SLAVE_WRITE_REQUESTED

In case backend is not ready, ie: fail to wakeup or initialization, on the returning of the I2C_SLAVE_WRITE_REQUESTED event, bus driver should aware the backend status and might auto sending NACK on the next incoming bytes for I2C master to retry.
