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.

You mean outside of public web access?

The report was done in a Matrix channel. I could provide the link to the
report for the Closes: tag, but it requires to sign-in to view it.

Okay, thanks for elaboration. In case of a new version, please mention this
in the cover letter.
