+Device Tree Clock bindings for Intel's SoCFPGA Stratix10 platform
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be
+	"intel,stratix10-clkmgr"
+
+- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
+
+- #clock-cells : from common clock binding, shall be set to 1.
+
+Example:
+	clkmgr: clock-controller@ffd10000 {
+		compatible = "intel,stratix10-clkmgr";
+		reg = <0xffd10000 0x1000>;
+		#clock-cells = <1>;
+	};
