- +* 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;
