How is this used?
+tx/rx-clock-name : should be "brg1"-"brg16" for internal clock source, + should be "clk1"-"clk28" for external clock source.
Perhaps you should be using the clock binding here and in other bindings?
+
+Example:
+
+ ucc_serial: ucc@2200 {
+ device_type = "serial";
+ compatible = "ucc_uart";
+ port-number = <1>;
+ rx-clock-name = "brg2";
+ tx-clock-name = "brg2";
+ };
