+LEDs connected to Broadcom BCM6328 controller
+
+Required properties:
+- compatible : should be : "brcm,bcm6328-leds".
+- #address-cells: must be 1
+- #size-cells: must be 0
+- reg: BCM6328 LED controller address and size.
+
+Optional properties:
+- brcm,serial-leds: enable Serial LEDs.
+
+Each led is represented as a sub-node of the brcm,bcm6328-leds device.
+
+LED sub-node properties:
+- reg : LED pin number (could be from 0 to 23).
+- compatible : should be : "brcm,bcm6328-led".
+
+Normal LED:
+- label (optional) : see Documentation/devicetree/bindings/leds/common.txt
+- active-low (optional) : LED is active low.
+- default-state (optional): see
+ Documentation/devicetree/bindings/leds/leds-gpio.txt
+- linux,default-trigger (optional): see
+ Documentation/devicetree/bindings/leds/common.txt
+
+Hardware controlled LED:
+- brcm,hardware-controlled (optional) : LED is hardware controlled.
+- brcm,link-selection (optional) : LED link selection values.
+- brcm,activity-selection (optional) : LED activity selection values.
