| +* Broadcom BCM6368 pin controller |
| + |
| +Required properties: |
| +- compatible: Must be "brcm,bcm6368-pinctrl". |
| +- reg: Register specifiers of dirout, dat, mode registers. |
| +- reg-names: Must be "dirout", "dat", "mode". |
| +- brcm,gpiobasemode: Phandle to the gpio basemode register. |
| +- gpio-controller: Identifies this node as a GPIO controller. |
| +- #gpio-cells: Must be <2>. |
| + |
| +Example: |
| + |
| +pinctrl: pin-controller@10000080 { |
| + compatible = "brcm,bcm6368-pinctrl"; |
| + reg = <0x10000080 0x08>, |
| + <0x10000088 0x08>, |
| + <0x10000098 0x04>; |
| + reg-names = "dirout", "dat", "mode"; |
| + brcm,gpiobasemode = <&gpiobasemode>; |
| + |
| + gpio-controller; |
| + #gpio-cells = <2>; |
| +}; |
| + |
| +gpiobasemode: syscon@100000b8 { |
| + compatible = "brcm,bcm6368-gpiobasemode", "syscon"; |
| + reg = <0x100000b8 4>; |
| + native-endian; |
