+* Pinctrl driver for the Marvell Berlin SoCs
+
+The pins controlled by the Marvell Berlin controller are organized in groups.
+Configuration is done by group, so no actual pin information is needed.
+
+Required properties:
+- compatible: "marvell-berlin2cd-pinctrl",
+ "marvell-berlin2-pinctrl",
+ "marvell-berlin2q-pinctrl"
+- reg: registers physical addresses and lengths of the pin controller.
+- reg-names: name of the register regions.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+A pinctrl should contains subnodes representing the pinctrl pin group
+configurations, one per group. Each subnode has the group name and the muxing
+function used.
+
+Required subnode-properties:
+- berlin,group: a string describing the group's name.
+- berlin,function: the function used to mux the group.
+ 0: function 0
+ 1: function 1
+ ...
+
+Example:
+
+pinctrl: pinctrl@0 {
+ compatible = "marvell,berlin2q-pinctrl";
+ reg = <0xea0000 0x08>, <0xfc0000 0x44>;
+ reg-names = "global_base", "sm_base";
+
+ uart0_pmux: uart0-pmux {
+ berlin,group = "GSM12";
+ berlin,function = <0>;
+ };
+}
+
+&uart0 {
+ pinctrl-0 = <&uart0_pmux>;
+ pinctrl-names = "default";
+};
