+* 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 : standard interrupt property.
+- clock-frequency : desired I2C bus clock frequency in Hz.
+
+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>;
+                };
+        };
