Subject: [PATCH v2 0/2] leds: Add control of the voltage/current regulator to the LED core
Date: Mon, 15 Jul 2019 17:56:55 +0200
Message-ID: <20190715155657.22976-1-jjhiblot@ti.com> (raw)

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
