The "gpio" trigger is used to control LEDs by the level of a GPIO input referenced by the trigger-sources property. This is already documented in the trigger-sources property description and is used in at least one devicetree (am335x-regor.dtsi). Document it so validation of those and future DTs will pass.

having Lee only in Cc in a longer patch series might make it difficult to notice this change. I guess this patch needs to be applied or at least "Acked-by" by them. Heiko
