1 LEDs connected to GPIO lines
4 - compatible : should be "gpio-leds".
6 Each LED is represented as a sub-node of the gpio-leds device.  Each
9 LED sub-node properties:
10 - gpios :  Should specify the LED's GPIO, see "gpios property" in
11   Documentation/devicetree/bindings/gpio/gpio.txt.  Active low LEDs should be
12   indicated using flags in the GPIO specifier.
13 - label :  (optional)
14   see Documentation/devicetree/bindings/leds/common.txt
15 - linux,default-trigger :  (optional)
16   see Documentation/devicetree/bindings/leds/common.txt
17 - default-state:  (optional) The initial state of the LED.  Valid
19   and the default-state property is set the to same value, then no
