+Device Tree bindings for Marvell PMU
+
+Required properties:
+ - compatible: value should be "marvell,dove-pmu".
+ - reg: two base addresses and sizes of the PM controller and PMU.
+ - interrupts: single interrupt number for the PMU interrupt
+ - interrupt-controller: must be specified as the PMU itself is an
+ interrupt controller.
+ - #interrupt-cells: must be 1.
+ - #reset-cells: must be 1.
+
+Optional properties:
+ - None
+
+Domain descriptions are listed as child nodes of the power management
+node. Each domain has the following properties:
+
+Required properties:
+ - #power-domain-cells: must be 0.
+
+Optional properties:
+ - marvell,pmu_pwr_mask: specifies the mask value for PMU power register
+ - marvell,pmu_iso_mask: specifies the mask value for PMU isolation register
+ - resets: points to the reset manager (PMU node) and reset index.
+
+Example:
+
+ pmu: power-management@d0000 {
+ compatible = "marvell,dove-pmu";
+ reg = <0xd0000 0x8000>, <0xd8000 0x8000>;
+ interrupts = <33>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ #reset-cells = <1>;
+
+ vpu_domain: vpu-domain {
+ #power-domain-cells = <0>;
+ marvell,pmu_pwr_mask = <0x00000008>;
+ marvell,pmu_iso_mask = <0x00000001>;
+ resets = <&pmu 16>;
+ };
+
+ gpu_domain: gpu-domain {
+ #power-domain-cells = <0>;
+ marvell,pmu_pwr_mask = <0x00000004>;
+ marvell,pmu_iso_mask = <0x00000002>;
+ resets = <&pmu 18>;
+ };
