+Raspberry Pi power domain driver
+
+Required properties:
+
+- compatible: Should be "raspberrypi,bcm2835-power".
+- firmware: Reference to the RPi firmware device node.
+- #power-domain-cells: Should be <1>, we providing multiple power domains.
+
+The valid defines for power domain are:
+
+ RPI_POWER_DOMAIN_USB
+
+Example:
+
+power: power {
+ compatible = "raspberrypi,bcm2835-power";
+ firmware = <&firmware>;
+ #power-domain-cells = <1>;
+};
+
+Example for using power domain:
+
+&usb {
+ power-domains = <&power RPI_POWER_DOMAIN_USB>;
+};
