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";
};
