Subject: [PATCH 2/2] dt-bindings: leds: document new "power-supply" property
Date: Mon, 8 Jul 2019 12:35:47 +0200 [thread overview]
Message-ID: <20190708103547.23528-3-jjhiblot@ti.com> (raw)
In-Reply-To: <20190708103547.23528-1-jjhiblot@ti.com>
Most of the LEDs are powered by a voltage/current regulator. describing in
the device-tree makes it possible for the LED core to enable/disable it
when needed.
