+* 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 {
|
|
