+Device tree configuration for the I2C controller on the XLP9xx/5xx SoC
+
+Required properties:
+- compatible      : should be "netlogic,xlp980-i2c"
+- reg             : bus address start and address range size of device
+- interrupts      : interrupt number
+
+Optional properties:
+- clock-frequency : frequency of bus clock in Hz
+                    Defaults to 100 KHz when the property is not specified
+
+Example:
+
+i2c0: i2c@113100 {
+	compatible = "netlogic,xlp980-i2c";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0 0x113100 0x100>;
+	clock-frequency = <400000>;
+	interrupts = <30>;
+	interrupt-parent = <&pic>;
+};
