+* Broadcom BCM6362 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>.
|
