+-----------------------------------------------------------
+Device Tree Bindings for the Xilinx Zynq MPSoC PM domains
+-----------------------------------------------------------
+The binding for zynqmp-power-controller follow the common
+generic PM domain binding[1].
+
+[1] Documentation/devicetree/bindings/power/power_domain.txt
+
+== Zynq MPSoC Generic PM Domain Node ==
+
+Required property:
+ - Below property should be in zynqmp-firmware node.
+ - #power-domain-cells: Number of cells in a PM domain specifier. Must be 1.
+
+Power domain ID indexes are mentioned in
+include/dt-bindings/power/xlnx-zynqmp-power.h.
+
+-------
+Example
+-------
+
+firmware {
+ zynqmp_firmware: zynqmp-firmware {
+ ...
+ #power-domain-cells = <1>;
+ ...
+ };
+};
+
+sata {
+ ...
+ power-domains = <&zynqmp_firmware 28>;
