  18 +* Broadcom BCM6358 pin controller
  19 +
  20 +Required properties:
  21 +- compatible: Must be "brcm,bcm6358-pinctrl".
  22 +- reg: Register specifiers of dirout, dat registers.
  23 +- reg-names: Must be "dirout", "dat".
  24 +- brcm,gpiomode: Phandle to the shared gpiomode register.
  25 +- gpio-controller: Identifies this node as a gpio-controller.
  26 +- #gpio-cells: Must be <2>.
  27 +
  28 +Example:
  29 +
  30 +pinctrl: pin-controller@fffe0080 {
  31 +       compatible = "brcm,bcm6358-pinctrl";
  32 +       reg = <0xfffe0080 0x8>,
  33 +             <0xfffe0088 0x8>,
  34 +             <0xfffe0098 0x4>;
  35 +       reg-names = "dirout", "dat";
  36 +       brcm,gpiomode = <&gpiomode>;
  37 +
  38 +       gpio-controller;
  39 +       #gpio-cells = <2>;
  40 +};
  41 +
  42 +gpiomode: syscon@fffe0098 {
  43 +       compatible = "brcm,bcm6358-gpiomode", "syscon";
  44 +       reg = <0xfffe0098 0x4>;
  45 +       native-endian;
