Marvell Armada 37xx Platforms Device Tree Bindings
--------------------------------------------------

Boards using a SoC of the Marvell Armada 37xx family must carry the
following root node property:

 - compatible: must contain "marvell,armada3710"

In addition, boards using the Marvell Armada 3720 SoC shall have the
following property before the previous one:

 - compatible: must contain "marvell,armada3720"

Example:

compatible = "marvell,armada-3720-db", "marvell,armada3720", "marvell,armada3710";


Power management
----------------

For power management (particularly DVFS and AVS), the North Bridge
Power Management component is needed:

Required properties:
- compatible     : should contain "marvell,armada-3700-nb-pm", "syscon";
- reg            : the register start and length for the North Bridge
		    Power Management

Example:

nb_pm: syscon@14000 {
	compatible = "marvell,armada-3700-nb-pm", "syscon";
	reg = <0x14000 0x60>;
}

AVS
---

For AVS an other component is needed:

Required properties:
- compatible     : should contain "marvell,armada-3700-avs", "syscon";
- reg            : the register start and length for the AVS

Example:
avs: avs@11500 {
	compatible = "marvell,armada-3700-avs", "syscon";
	reg = <0x11500 0x40>;
}
