+* Broadcom BCM63268 pin controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: Must be "brcm,bcm6362-pinctrl".
|
|
+- reg: Register specifiers of dirout, dat, led, mode, ctrl, basemode registers.
|
|
+- reg-names: Must be "dirout", "dat", "led", "mode", "ctrl", "basemode".
|
|
+- gpio-controller: Identifies this node as a GPIO controller.
|
|
+- #gpio-cells: Must be <2>.
|
|
+
|
|
+Example:
|
|
+
|
|
+pinctrl: pin-controller@100000c0 {
|
|
+ compatible = "brcm,bcm63268-pinctrl";
|
|
+ reg = <0x100000c0 0x8>,
|
|
+ <0x100000c8 0x8>,
|
|
+ <0x100000d0 0x4>,
|
|
+ <0x100000d8 0x4>,
|
|
+ <0x100000dc 0x4>,
|
|
+ <0x100000f8 0x4>;
|
|
+ reg-names = "dirout", "dat", "led", "mode",
|
|
+ "ctrl", "basemode";
|
|
+
|
|
+ gpio-controller;
|
|
+ #gpio-cells = <2>;
