Marvell Dove Platforms Device Tree Bindings
-----------------------------------------------
Boards with a Marvell Dove SoC shall have the following properties:
Required root node property:
- compatible: must contain "marvell,dove";
* Global Configuration registers
Global Configuration registers of Dove SoC are shared by a syscon node.
Required properties:
- compatible: must contain "marvell,dove-global-config" and "syscon".
- reg: base address and size of the Global Configuration registers.
Example:
gconf: global-config@e802c {
compatible = "marvell,dove-global-config", "syscon";
reg = <0xe802c 0x14>;
};
