+* Texas Instruments Davinci I2C
+
+This file provides information, what the device node for the
+davinci i2c interface contain.
+
+Required properties:
+- compatible: "ti,davinci-i2c";
+- reg : Offset and length of the register set for the device
+
+Recommended properties :
+- interrupts : <a> standard interrupt property.
+- clock-frequency : desired I2C bus clock frequency in Hz.
+
+Optional properties:
+- bus-delay: bus delay in usec
+
+Example (enbw_cmc board):
+	i2c@1c22000 {
+		compatible = "ti,davinci-i2c";
+		reg = <0x22000 0x1000>;
+		clock-frequency = <100000>;
+		interrupts = <15>;
+		interrupt-parent = <&intc>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		dtt@48 {
+				compatible = "national,lm75";
+				reg = <0x48>;
+			};
+	};
