1 Device Tree bindings for Marvell PMU
4 - compatible: value should be "marvell,dove-pmu".
5 May also include "simple-bus" if there are child devices, in which
6 case the ranges node is required.
7 - reg: two base addresses and sizes of the PM controller and PMU.
8 - interrupts: single interrupt number for the PMU interrupt
9 - interrupt-controller: must be specified as the PMU itself is an
11 - #interrupt-cells: must be 1.
12 - #reset-cells: must be 1.
13 - domains: sub-node containing domain descriptions
16 - ranges: defines the address mapping for child devices, as per the
17 standard property of this name. Required when compatible includes
20 Power domain descriptions are listed as child nodes of the "domains"
21 sub-node. Each domain has the following properties:
24 - #power-domain-cells: must be 0.
27 - marvell,pmu_pwr_mask: specifies the mask value for PMU power register
28 - marvell,pmu_iso_mask: specifies the mask value for PMU isolation register
29 - resets: points to the reset manager (PMU node) and reset index.
