Marvell Prestera Switch Chip bindings
-------------------------------------

Required properties:
- compatible: one of the following
	"marvell,prestera-98dx3236",
	"marvell,prestera-98dx3336",
	"marvell,prestera-98dx4251",
- reg: address and length of the register set for the device.
- interrupts: interrupt for the device

Optional properties:
- dfx: phandle reference to the "DFX Server" node

Example:

switch {
	compatible = "simple-bus";
	#address-cells = <1>;
	#size-cells = <1>;
	ranges = <0 MBUS_ID(0x03, 0x00) 0 0x100000>;

	packet-processor@0 {
		compatible = "marvell,prestera-98dx3236";
		reg = <0 0x4000000>;
		interrupts = <33>, <34>, <35>;
		dfx = <&dfx>;
	};
};

DFX Server bindings
-------------------

Required properties:
- compatible: must be "marvell,dfx-server", "simple-bus"
- ranges: describes the address mapping of a memory-mapped bus.
- reg: address and length of the register set for the device.

Example:

dfx-server {
	compatible = "marvell,dfx-server", "simple-bus";
	#address-cells = <1>;
	#size-cells = <1>;
	ranges = <0 MBUS_ID(0x08, 0x00) 0 0x100000>;
	reg = <MBUS_ID(0x08, 0x00) 0 0x100000>;
};
