+* Broadcom BCM6328 pin controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: Must be "brcm,bcm6328-pinctrl".
|
|
+- reg: Register specifies of dirout, dat, mode, mux registers.
|
|
+- reg-names: Must be "dirout", "dat", "mode", "mux".
|
|
+- gpio-controller: Identifies this node as a GPIO controller.
|
|
+- #gpio-cells: Must be <2>
|
|
+
|
|
+Example:
|
|
+
|
|
+pinctrl: pin-controller@10000080 {
|
|
+ compatible = "brcm,bcm6328-pinctrl";
|
|
+ reg = <0x10000080 0x8>,
|
|
+ <0x10000088 0x8>,
|
|
+ <0x10000098 0x4>,
|
|
+ <0x1000009c 0xc>;
|
|
+ reg-names = "dirout", "dat", "mode", "mux";
|
|
+
|
|
+ gpio-controller;
|
|
+ #gpio-cells = <2>;
