-For various board the "board" node may contain specific properties
-that pertain to this particular board, such as board-specific GPIOs.
-
-Required root node property: src
-- Nomadik System and reset controller used for basic chip control, clock
-  and reset line control.
-- compatible: must be "stericsson,nomadik,src"
-
-Boards with the Nomadik SoC include:
-
-Nomadik NHK-15 board manufactured by ST Microelectronics:
-
-Required root node property:
-
-compatible="st,nomadik-nhk-15";
-
-S8815 "MiniKit" manufactured by Calao Systems:
-
-Required root node property:
-
-compatible="calaosystems,usb-s8815";
-
-Required node: usb-s8815
-
-Example:
-
-usb-s8815 {
-		ethernet-gpio {
-			gpios = <&gpio3 19 0x1>;
-			interrupts = <19 0x1>;
-			interrupt-parent = <&gpio3>;
