| +* 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>; |
