PLL divider based Dove clocks
Marvell Dove has a 2GHz PLL, which feeds into a set of dividers to provide
high speed clocks for a number of peripherals. These dividers are part of
the PMU, and thus this node should be a child of the PMU node.
The following clocks are provided:
ID Clock
-------------
0 AXI bus clock
1 GPU clock
2 VMeta clock
3 LCD clock
Required properties:
- compatible : shall be "marvell,dove-divider-clock"
- reg : shall be the register address of the Core PLL and Clock Divider
Control 0 register. This will cover that register, as well as the
Core PLL and Clock Divider Control 1 register. Thus, it will have
a size of 8.
- #clock-cells : from common clock binding; shall be set to 1
divider_clk: core-clock@0064 {
compatible = "marvell,dove-divider-clock";
reg = <0x0064 0x8>;
#clock-cells = <1>;
};

Device Tree bindings for Marvell PMU
Required properties:
- compatible: value should be "marvell,dove-pmu".
May also include "simple-bus" if there are child devices, in which
case the ranges node is required.
- 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.
- domains: sub-node containing domain descriptions
Optional properties:
- ranges: defines the address mapping for child devices, as per the
standard property of this name. Required when compatible includes
"simple-bus".
Power domain descriptions are listed as child nodes of the "domains"
sub-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>;
domains {
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>;
};
};
