+Marvell Prestera Switch Chip bindings
+-------------------------------------
+
+Required properties:
+- compatible: must be "marvell,prestera" and 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", "marvell,prestera";
+		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>;
+};
+
+Marvell Prestera SwitchDev bindings
+-----------------------------------
+Optional properties:
+- compatible: must be "marvell,prestera"
+- base-mac-provider: describes handle to node which provides base mac address,
+	might be a static base mac address or nvme cell provider.
+
+Example:
+
+eeprom_mac_addr: eeprom-mac-addr {
+       compatible = "eeprom,mac-addr-cell";
+       status = "okay";
+
+       nvmem = <&eeprom_at24>;
+};
+
+prestera {
+       compatible = "marvell,prestera";
+       status = "okay";
+
+       base-mac-provider = <&eeprom_mac_addr>;
+};
+
+The current implementation of Prestera Switchdev PCI interface driver requires
+that BAR2 is assigned to 0xf6000000 as base address from the PCI IO range:
+
+&cp0_pcie0 {
+	ranges = <0x81000000 0x0 0xfb000000 0x0 0xfb000000 0x0 0xf0000
+		0x82000000 0x0 0xf6000000 0x0 0xf6000000 0x0 0x2000000
+		0x82000000 0x0 0xf9000000 0x0 0xf9000000 0x0 0x100000>;
+	phys = <&cp0_comphy0 0>;
+	status = "okay";
+};
