+TMP108 temperature sensor
+-------------------------
+
+This device supports I2C only.
+
+Requires node properties:
+- compatible : "ti,tmp108"
+- reg : the I2C address of the device. This is 0x48, 0x49, 0x4a, or 0x4b.
+
+Example:
+       tmp108@48 {
+               compatible = "ti,tmp108";
+               reg = <0x48>;
+       };
