+* Marvell Kirkwood SoC pinctrl driver for mpp
+
+Please refer to marvell,mvebu-pinctrl.txt in this directory for common binding
+part and usage.
+
+Required properties:
+- compatible: "marvell,88f6180-pinctrl",
+              "marvell,88f6190-pinctrl", "marvell,88f6192-pinctrl",
+              "marvell,88f6281-pinctrl", "marvell,88f6282-pinctrl"
+
+This driver supports all kirkwood variants, i.e. 88f6180, 88f619x, and 88f628x.
+
+Available mpp pins/groups and functions:
+Note: brackets (x) are not part of the mpp name for marvell,function and given
