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

[Will Whang <will@willwhang.com>]

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**
