ST-Ericsson Nomadik Device Tree Bindings 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>; }; mmcsd-gpio { gpios = <&gpio3 16 0x1>; }; };
