Olimex A20-OLinuXino based boards (MICRO, SOM, SOM204, LIME2) commes with populated LED connected to AXP209. By default the LED is controlled by AXP209, so this binding actually doesn't modify any registers. However this can can be used as general purpose LED, if the control mode is overridden. Also this binding is enabled only for OLIMEX boards, since I have no knowlegde if the other manifactures are populating this LED.
