 +====== Device tree support ======
 +Device tree is the new method for describing non-discoverable hardware in Linux. This replaces former structure based method. For configuring a device using this drivers please follow the example bellow: 
 +
 +<code>
 +/dts-v1/;
 +/plugin/;
 +
 +/ {
 +
 + fragment@0 {
 + target-path = "/";
 + dvdd: fixedregulator@0 {

 + regulator-min-microvolt = <3300000>;
 + regulator-max-microvolt = <3300000>;
 + regulator-boot-on;
 + };
 + };
 +
 + fragment@1 {

 + avdd: fixedregulator@1 {
 + compatible = "regulator-fixed";

 + regulator-min-microvolt = <3300000>;
 + regulator-max-microvolt = <3300000>;
 + regulator-boot-on;
 + };
 + };
 +
 + fragment@3 {

 +</code>
 +
 +<note important> Interrupt pin connection - interrupts = <25 0x2>; this line means that gpio pin 25 is used for the interrupt and it must be connect to the DOUT/RDY pin of AD7192 along with the SPI MISO.
