+* Broadcom BCM6358 pin controller
+
+Required properties:
+- compatible: Must be "brcm,bcm6358-pinctrl".
+- reg: Register specifiers of dirout, dat registers.
+- reg-names: Must be "dirout", "dat".
+- brcm,gpiomode: Phandle to the shared gpiomode register.
+- gpio-controller: Identifies this node as a gpio-controller.
+- #gpio-cells: Must be <2>.
+
+Example:
+
+pinctrl: pin-controller@fffe0080 {
+ compatible = "brcm,bcm6358-pinctrl";
+ reg = <0xfffe0080 0x8>,
+ <0xfffe0088 0x8>,
+ <0xfffe0098 0x4>;
+ reg-names = "dirout", "dat";
+ brcm,gpiomode = <&gpiomode>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+};
+
+gpiomode: syscon@fffe0098 {
+ compatible = "brcm,bcm6358-gpiomode", "syscon";
+ reg = <0xfffe0098 0x4>;
+ native-endian;
+};
