Please use just "see Documentation/devicetree/bindings/leds/common.txt"
as a description of this property.

> +- default-state: The initial state of the LED see common.txt

Please use just "Documentation/devicetree/bindings/leds/leds-gpio.txt"
as a description of this property.

> +- linux,default-trigger: Linux trigger, see common.txt

Please use just "see Documentation/devicetree/bindings/leds/common.txt"
as a description of this property.
