+Bindings for LEDs on CZ.NIC's Turris Omnia
+
+Required properties:
+ - compatible : Should be "cznic,turris-omnia-leds"
+ - reg : I2C slave address
+
+Optional properties (required if any sub-nodes are given):
+ - #address-cells : Should be 1
+ - #size-cells : Should be 0
+
+LED sub-nodes can be given for LEDs for which label shall be non-default or
+for which default-trigger is to be set.
+
+LED sub-node properties:
+ - reg : Must be from 0x0 to 0xb, since there are 12 LEDs on this
+ controller.
+ - label : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+ - linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Example:
+
+ led-controller@2b {
+ compatible = "cznic,turris-omnia-leds";
+ reg = <0x2b>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ led@0 {
+ reg = <0>;
+ label = "omnia::heartbeat";
+ linux,default-trigger = "heartbeat";
+ };
+ };
