[GIT PULL v2 for 5.15] Camera sensor, async and documentation patches

[Sakari Ailus]

Hi Mauro,

Here's a large set of patches for 5.15.

Notable changes include:

- Drivers for imx335, imx412 and ov9282 sensors
- Fixes for digital gain configuration in ov2740 and ov9734 drivers
- Fix ov8856 driver for ACPI
- Shorten V4L2 async notifier functions for better fitting under 80 chars
- Documentation improvements (camera sensors, CSI-2)
- V4L2 LED flash fixes
- Manual CSI-2 LP-11/LP-111 mode support with runtime PM, CCS driver
  support
- Correct mbus code for YUV output in ov5640 driver with CSI-2
- Switch to DEVICE_ATTR_RO and DEVICE_ATTR_RW in MC and a few drivers
- Omap3isp error path bugfix

since v1:

- Rebased on media-stage tree
- Include Niklas's rcar-vin patches
- Added imx258 fixes by Umang Jain and Laurent Pinchart

Please pull.

Partially applied.

The RCar patches were adding new warnings. So, I ended not applying
them:

0008-0043-media-dt-bindings-media-renesas-csi2-Add-r8a779a0-su.patch
0009-0043-rcar-csi2-Add-r8a779a0-support.patch
0010-0043-rcar-vin-Refactor-controls-creation-for-video-device.patch
0011-0043-rcar-vin-Fix-error-paths-for-rvin_mc_init.patch
0012-0043-rcar-vin-Improve-async-notifier-cleanup-paths.patch
0013-0043-rcar-vin-Improve-reuse-of-parallel-notifier.patch
0014-0043-rcar-vin-Rename-array-storing-subdevice-information.patch
0015-0043-rcar-vin-Move-group-async-notifier.patch
0016-0043-rcar-vin-Extend-group-notifier-DT-parser-to-work-wit.patch
0017-0043-rcar-vin-Create-a-callback-to-setup-media-links.patch
0018-0043-rcar-vin-Specify-media-device-ops-at-group-creation-.patch
0019-0043-rcar-vin-Move-and-rename-CSI-2-link-notifications.patch
0020-0043-rcar-vin-Add-r8a779a0-support.patch

Maybe due to that, those patches also didn't apply:
0029-0043-v4l-async-Rename-async-nf-functions-clean-up-long-li.patch
0030-0043-media-rcar-vin-Remove-explicit-device-availability-c.patch
0031-0043-media-v4l2-fwnode-Simplify-v4l2_async_nf_parse_fwnod.patch

Thanks,
