----------------------------------------------------------------------
Boards with a SoC of the Marvell 98DX3236, 98DX3336 and 98DX4251 families
shall have the following property:
Required root node property:
compatible: must contain "marvell,armadaxp-98dx3236"
In addition, boards using the Marvell 98DX3336 SoC shall have the
following property:
Required root node property:
compatible: must contain "marvell,armadaxp-98dx3336"

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"
- reg: address and length of the register set for the device.
Example:
dfx-registers {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 MBUS_ID(0x08, 0x00) 0 0x100000>;
dfx: dfx@0 {
compatible = "marvell,dfx-server";
reg = <0 0x100000>;
};
};

* DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
* boards were delivered with an older version of the bootloader that
* left internal registers mapped at 0xd0000000. If you are in this
* situation, you should either update your bootloader (preferred
* solution) or the below Device Tree should be adjusted.
