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
7 node's name represents the name of the corresponding LED.
9 LED sub-node properties:
10 - gpios : Should specify the LED's GPIO, see "Specifying GPIO information
11 for devices" in Documentation/powerpc/booting-without-of.txt. Active
12 low LEDs should be indicated using flags in the GPIO specifier.
13 - label : (optional) The label for this LED. If omitted, the label is
14 taken from the node name (excluding the unit address).
15 - linux,default-trigger : (optional) This parameter, if present, is a
16 string defining the trigger assigned to the LED. Current triggers are:
17 "backlight" - LED will act as a back-light, controlled by the framebuffer
19 "default-on" - LED will turn on
20 "heartbeat" - LED "double" flashes at a load average based rate
21 "ide-disk" - LED indicates disk activity
22 "timer" - LED flashes at a fixed, configurable rate
