-Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate
-boards (Example: 2Big/5Big Network v2, 2Big NAS).
-
-Required properties:
-- compatible: "lacie,netxbig-leds".
-- gpio-ext: Phandle for the gpio-ext bus.
-
-Optional properties:
-- timers: Timer array. Each timer entry is represented by three integers:
-  Mode (gpio-ext bus), delay_on and delay_off.
-
-Each LED is represented as a sub-node of the netxbig-leds device.
-
-Required sub-node properties:
-- mode-addr: Mode register address on gpio-ext bus.
-- mode-val: Mode to value mapping. Each entry is represented by two integers:
-  A mode and the corresponding value on the gpio-ext bus.
-- bright-addr: Brightness register address on gpio-ext bus.
-- max-brightness: Maximum brightness value.
-
-Optional sub-node properties:
-- label: Name for this LED. If omitted, the label is taken from the node name.
-- linux,default-trigger: Trigger assigned to the LED.
