Subject: [PATCH v2 0/2] iio: light: add support for veml3235
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.

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@gmail.com
