This series adds support for the Vishay veml3235 ambient light sensor with I2C protocol interface. I attempted to add support for this device in the existing veml6030 driver, as it shares some operating principles with the supported devices. But given that the veml3235 has different register addresses, bit arrangements, and limited functionality, it ended up making most of the driver kind of device-agnostic. Instead, the proposed driver is based on the recently updated veml6030 with multiple simplifications and a few clean ups (e.g. regfields, right definition of shared-by-all info masks, which can't be modified in veml6030 as it breaks the ABI). On the other hand, the dt-bindings can be recycled as there is no real reason to add new ones. From a dt-bindings point of view it resembles the already supported veml7700. But if for whatever reason new bindings would be preferred, I am willing to provide them in further versions. Signed-off-by: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx> --- Changes in v3: - Add missing Tag to [1/2] (Acked-by). - Drop processed values from the driver, which in turn removes the need to store the current resolution, gain and integration time in the driver data. - Fix SD0 bit position (15). - Drop redundant configuration write in hw_init (gain and integration times are the only fields to set). - Link to v2: https://lore.kernel.org/r/20241020-veml3235-v2-0-4bc7cfad7e0b@xxxxxxxxx Changes in v2: - Rename SD/SD0 bits to include register name. - Switch to dev_info() when checking ID. - Simplify val/val2 handling in veml3235_set_gain(). - Move return -EINVAL to the default case in veml3235_read_avail(). - Link to v1: https://lore.kernel.org/r/20241016-veml3235-v1-0-b904f802daef@xxxxxxxxx --- Javier Carrasco (2): dt-bindings: iio: light: veml6030: add veml3235 iio: light: add support for veml3235 .../bindings/iio/light/vishay,veml6030.yaml | 5 +- MAINTAINERS | 6 + drivers/iio/light/Kconfig | 11 + drivers/iio/light/Makefile | 1 + drivers/iio/light/veml3235.c | 504 +++++++++++++++++++++ 5 files changed, 526 insertions(+), 1 deletion(-) --- base-commit: ceab669fdf7b7510b4e4997b33d6f66e433a96db change-id: 20241007-veml3235-0a38265e9bae Best regards, -- Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx>
