Subject: [PATCH v3 0/3] iio: light: add support for VEML6075 UVA and UVB
 light sensor

This series adds support for the Vishay VEML6075 ultraviolet sensor,
which offers UVA and UVB measurement channels and I2C communication.

The device bindings and a simple example are also provided.

This driver has been tested with a Gravity VEML6075 UV Sensor Module in
open air conditions.

Changes in v3:
- veml6075.c: use MICRO instead of 1000000LL (add linux/units.h).
- veml6075.c: improve lock description.
- veml6075.c: remove unnecessary i2c_get_client_data() from the probe
  function.
- veml6075.c: remove shutdown function and do the bit update inline.
- veml6075.c: improve return path in read/write_raw().
- veml6075.c: remove -ENODEV return check for regulator_get_enable().
- Link to v2: https://lore.kernel.org/r/20231110-veml6075-v2-0-d04efbc8bf51@gmail.com

Changes in v2:
- General: swap patch order (bindings first).
- iio core: add uva and uvb modifiers.
- veml6075.c: use uva and uvb modifiers instead of extend_name
- veml6075.c: remove redundant information from the description.
- veml6075.c: inline device name.
- veml6075.c: use read_avail() for available attributes.
- veml6075.c: use guard(mutex) instead of lock/unlock().
- veml6075.c: use regulator_get_enable() without _optional.
- veml6075.c: register managed iio device and delete remove().
- veml6075.c: remove remaining debug messages.
- veml6075.c: error path cleanup (return type after val assignment).
- veml6075.c: remove zero from i2c_device_id.
- MAINTAINERS: fix bindings name.
- vishay,veml6075.yaml: remove vdd-supply description and mark property
  as true.
- Link to v1: https://lore.kernel.org/r/20231110-veml6075-v1-0-354b3245e14a@gmail.com
