  35 Example:
  36
  37 power: power {
  38         compatible = "raspberrypi,bcm2835-power";
  39         firmware = <&firmware>;
  40         #power-domain-cells = <1>;
  41 };
  42
  43 Example for using power domain:
  44
  45 &usb {
  46        power-domains = <&power RPI_POWER_DOMAIN_USB>;
  47 };
