+Device Tree Clock bindings for Marvell Berlin clocks
+
+This binding uses the common clock binding[1].

+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible: shall be one of the following:
+	"marvell,berlin2-pll",
+	"marvell,berlin2q-pll":
+		CPU PLL and System PLL
+- reg: Address and length of the clock register set.
+- #clock-cells: from common clock binding; shall be set to 0.
+- clocks: from common clock binding
+
+smclk: sysmgr-clock {
+	compatible = "fixed-clock";
+	#clock-cells = <0>;
+	clock-frequency = <25000000>;
+};
