IMHO, the right way is to get of_serial.c from linux and put some records 
like this 
 uarta: serial@70006000 {
                compatible = "nvidia,tegra20-uart";
                reg = <0x70006000 0x40>;
                reg-shift = <2>;
                interrupts = <0 36 0x04>;
                nvidia,dma-request-selector = <&apbdma 8>;
                clocks = <&tegra_car 6>;
                status = "disabled";
  };

to arch/arm/dts/tegra20.dtsi.
