[PATCH v3 0/2] iio: light: veml3328: add support for new sensor

[Joshua Crofts]

This patch series adds support for the Vishay VEML3328 RGBCIR light
sensor. The sensor communicates via I2C (SMBus compatible) and provides
5 types of 16-bit measurements: red, green, blue, clear and infrared.

Reasons for adding a new driver:
- Existing Vishay drivers in the kernel do not cover sensors that
  handle RGBC and IR simultaneously.
- The register map and configuration differ from other Vishay light
  sensors currently supported by IIO.

Testing:
- Tested on a Raspberry Pi 4 using a VEML3328 breakout board.

Changes in v2:
- Add additional IIO_LIGHT channel for ambient light sensing
- Remove separate dt binding file and added veml3328 entry to veml6030
  yaml
- Move driver to PM_RUNTIME_ACQUIRE_AUTOSUSPEND() macro
- Add missing headers
- Remov redundant mutex as regmap handles it itself
- Use regmap_set/clear_bits() instead of regmap_update_bits()
- Removed redundant dev pointer
- Edit commit messages
- Various code style cleanups
- Link to v1: https://patch.msgid.link/20260516-veml3328-v1-0-1d4b663e2fe3@xxxxxxxxx

Changes in v3:
- Add 2D array of precomputed scale values based on integration time
- Fix chan_spec masks
- Simplify read/write/avail callbacks
