Subject: [PATCH v2 0/2] leds: Add control of the voltage/current regulator to the LED core

This series makes it possible for the LED core to manage the power supply
of a LED. It uses the regulator API to disable/enable the power if when the
LED is turned on/off.
This is especially useful in situations where the LED driver/controller is
not supplying the power.

changes in v2:
- use devm_regulator_get_optional() to avoid using the dummy regulator and do
  some unnecessary work

Jean-Jacques Hiblot (2):
  dt-bindings: leds: document the "power-supply" property
  leds: Add control of the voltage/current regulator to the LED core
