Subject: [PATCH v2 0/4] media: Add Sony IMX585 image sensor support

Hi all,

This is v2 of the IMX585 series. It adds ClearHDR controls, fixes mono
format handling, and ensures HCG can’t be enabled while HDR is active.

Changes in v2:
  - Move to V4L2 active State API.
  - Shift the I2C registers read/write to v4l2-cci.
  - Remove IR Filter switch support.
  - Various log/trace noise trimmed or moved to debug print.
  - Lock/ignore HCG when HDR is enabled; mark control inactive.
  - Using compatible string for mono sensor.
  - dt-bindings: drop redundant maxItems/minItems/names,
    add "sony,imx585-mono", fix quoted string lint.

Features
==========
  * 4-lane or 2-lane MIPI-CSI-2 up to 2079 Mbps/lane
  * 4 K @ 60 fps 12-bit linear, 4 K @ 30 fps 16-bit Clear-HDR,
    4 K @ 30 fps 12-bit gradient compression Clear-HDR
    1080p binning mode, mono hardware variant, HCG support.
  * New Sensor Dependent V4L2 controls for
    HDR blending, grad-compression, HCG enable and Enable ClearHDR.
  * Blacklevel adjustments through V4L2_CID_BRIGHTNESS.
  * Multi Camera synchronization mode support.

Testing
==========
  - Platform: Raspberry Pi 5, 4 lanes
  - Formats: Y12/Y16 (mono), SRGGB12/SRGGB16 (color)
  - Verified HDR on/off toggling updates ranges (exposure/gain/HMAX/VMAX)
  - HCG is inactive and ignored when HDR=1; active in normal mode

Series layout
=============
  1. **dt-bindings: media: Add Sony IMX585 CMOS image sensor**
  2. **media: uapi: Add custom IMX585 control IDs**
  3. **media: i2c: imx585: Add Sony IMX585 image-sensor driver**
  4. **media: docs: Add userspace-API guide for the IMX585 driver**
