[PATCH v4 0/7] iio: light: vcnl4000: add regulator support

[Erikas Bitovtas <xerikasxx@gmail.com>]

This patch series introduces support for voltage supply, I2C and cathode
regulators. This fixes an issue where if a regulator is shared between
the proximity sensor and some other device, and the other device is
powered off, the proximity sensor would be powered off as well.

One of the commits includes a Reported-by: tag without a Closes: tag -
the report was done outside of LKML.

Changes in v4:
- Reworded device tree bindings commit into imperative mood and
  clarified where do supplies come from.
- Moved data->chip_spec->set_power_state() calls from init functions to
  probe.
- Removed explicit less than 0 checks for ret where unnecessary.
- Moved the patch that adds regulators to the end of the series.
- Added an explanation for removing duplicate prints in probe.
- Fixed indentation for devm_regulator_bulk_get_enable() and i2c_smbus
  writes in vcnl4200_init().
- Removed a redundant check for "proximity-near-level" device property.
- Link to v3: https://lore.kernel.org/r/20260314-vcnl4000-regulators-v3-0-3c4a48d30676@gmail.com

Changes in v3:
- Added a more detailed description for supplies in the dt-bindings commit.
- Separated sorting includes into a commit of its own.
- Replaced all occurrences of mutex_init with its device-managed
  counterpart.
- Moved client->dev variable declaration into a commit for adding
  regulators.
- Removed redundant dev_err messages in probe function.
- Replaced all direct usages of client->dev and data->client into usages
  by variable.
- Link to v2: https://lore.kernel.org/r/20260312-vcnl4000-regulators-v2-0-2bdebbcbb58a@gmail.com

Changes in v2:
- Removed double quotes in includes.
