title: What is the meaning of a phandle when used as device tree node name?
body: <p>This code snippet comes from the device tree for the RIoTBoard (<code>/arch/arm/boot/dts/imx6dl-riotboard.dts</code>)</p>
  
  <pre><code>&amp;hdmi {
           ddc-i2c-bus = &lt;&amp;i2c2&gt;;
           status = "okay";
  };
  </code></pre>
  
  <p>I have gone through the device tree documentation both on devicetree.org and in the documentation/devicetree folder of the linux kernel, but I am not able to find any description of the meaning of a phandle when used as node name.</p>
