+Currently defined compatibles:
+- t1040-ucc-uart
+
+Properties for t1040-ucc-uart:
+port-number : port number of UCC-UART
+tx/rx-clock-name : should be "brg1"-"brg16" for internal clock source,
+		   should be "clk1"-"clk28" for external clock source.
+
+Example:
+
+	ucc_serial: ucc@2200 {
+		compatible = "t1040-ucc-uart";
+		port-number = <0>;
+		rx-clock-name = "brg2";
+		tx-clock-name = "brg2";
+	};
