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>;
}
