10   - Linus Walleij <linus.walleij@linaro.org>
13   Regulator LEDs are powered by a single regulator such that they can
14   be turned on or off by enabling or disabling the regulator. The available
16   regulator, and any constraints on the voltage or current will need to be
17   specified on the regulator.
