+* Serial
+
+Required Properties:
+compatible : must be "fsl,<chip>-ucc-uart". For t1040, must be
+"fsl,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 = "fsl,t1040-ucc-uart";
+ port-number = <0>;
+ rx-clock-name = "brg2";
+ tx-clock-name = "brg2";
+ };
