a=ed25519; pk=RTDOoVwgeL4oFdASj9U+cxJuIjXuXk73zkjnGOJKbEo= 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. Datasheet: https://www.vishay.com/docs/84968/veml3328.pdf Signed-off-by: Joshua Crofts --- Changes in v4: - Fix PM_RUNTIME_ACQUIRE_AUTOSUSPEND() macro cleanup scope - Add mutex to prevent race in veml3328_write_raw() - Link to v3: https://lore.kernel.org/r/20260530-veml3328-v3-0-dd562eaee8d9@gmail.com 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@gmail.com Changes in v3: - Add 2D array of precomputed scale values based on integration time - Fix chan_spec masks - Simplify read/write/avail callbacks Signed-off-by: Joshua Crofts --- Joshua Crofts (2): dt-bindings: iio: light: veml6030: add veml3328 iio: light: veml3328: add support for new device .../bindings/iio/light/vishay,veml6030.yaml | 5 +- MAINTAINERS | 5 + drivers/iio/light/Kconfig | 11 + drivers/iio/light/Makefile | 1 + drivers/iio/light/veml3328.c | 422 +++++++++++++++++++++ 5 files changed, 443 insertions(+), 1 deletion(-) --- base-commit: 7b84b1e9dd850a5c9b55e27daa4ecdc2dd5b3431 change-id: 20260530-veml3328-d2ccb26d02c7 Best regards, -- Joshua Crofts
