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>;
|
|
}
