title: How to specify the device name for uart in device tree(.dts) file?
body: <p>I was compiling the OpenWrt (A wireless router based on Linux), i added a board to the OpenWrt source, my board has two uart ports, i can declare and enable the two uart ports, the two uart ports are named 'uartfull' and 'uartlite'. </p>
  
  <p>The 'uartlite' is registered to '/dev/ttyS1', and the 'uartfull' is registered to '/dev/ttyS0'. But i want uartlite to '/dev/ttyS0' and 'uartfull' to '/dev/ttyS1'.</p>
  
  <pre><code>    uartlite@c00 {
          compatible = "ralink,rt5350-uart", "ralink,rt2880-uart", "ns16550a";
          reg = &lt;0xc00 0x100&gt;;
  
          resets = &lt;&amp;rstctrl 19&gt;;
          reset-names = "uartl";
  
          interrupt-parent = &lt;&amp;intc&gt;;
          interrupts = &lt;12&gt;;
  
          reg-shift = &lt;2&gt;;
      };
  
      uart@500 {
          compatible = "ralink,rt5350-uart", "ralink,rt2880-uart", "ns16550a";
          reg = &lt;0x500 0x100&gt;;
  
          resets = &lt;&amp;rstctrl 12&gt;;
          reset-names = "uart";
  
          interrupt-parent = &lt;&amp;intc&gt;;
          interrupts = &lt;5&gt;;
  
          reg-shift = &lt;2&gt;;
  
          status = "okay";
      };
  </code></pre>
  
  <p>This is the 'uartfull'(name uart) and the 'uartlite' node in my dts file. I was guessing what determines the device name(/dev/ttyS0 /dev/ttyS1 and so on), can i force a device name for this two uart nodes.</p>
