1 Marvell Prestera Switch Chip bindings
2 -------------------------------------
4 Required properties:
5 - compatible: must be "marvell,prestera" and one of the following
6         "marvell,prestera-98dx3236",
7         "marvell,prestera-98dx3336",
8         "marvell,prestera-98dx4251",
9 - reg: address and length of the register set for the device.
10 - interrupts: interrupt for the device
12 Optional properties:
13 - dfx: phandle reference to the "DFX Server" node
15 Example:
17 switch {
18         compatible = "simple-bus";
19         #address-cells = <1>;
20         #size-cells = <1>;
21         ranges = <0 MBUS_ID(0x03, 0x00) 0 0x100000>;
23         packet-processor@0 {
24                 compatible = "marvell,prestera-98dx3236", "marvell,prestera";
25                 reg = <0 0x4000000>;
26                 interrupts = <33>, <34>, <35>;
27                 dfx = <&dfx>;
28         };
31 DFX Server bindings
32 -------------------
34 Required properties:
35 - compatible: must be "marvell,dfx-server", "simple-bus"
36 - ranges: describes the address mapping of a memory-mapped bus.
37 - reg: address and length of the register set for the device.
39 Example:
41 dfx-server {
42         compatible = "marvell,dfx-server", "simple-bus";
43         #address-cells = <1>;
44         #size-cells = <1>;
45         ranges = <0 MBUS_ID(0x08, 0x00) 0 0x100000>;
46         reg = <MBUS_ID(0x08, 0x00) 0 0x100000>;
49 Marvell Prestera SwitchDev bindings
50 -----------------------------------
51 Optional properties:
52 - compatible: must be "marvell,prestera"
53 - base-mac-provider: describes handle to node which provides base mac address,
54         might be a static base mac address or nvme cell provider.
56 Example:
58 eeprom_mac_addr: eeprom-mac-addr {
59        compatible = "eeprom,mac-addr-cell";
60        status = "okay";
62        nvmem = <&eeprom_at24>;
65 prestera {
66        compatible = "marvell,prestera";
67        status = "okay";
69        base-mac-provider = <&eeprom_mac_addr>;
72 The current implementation of Prestera Switchdev PCI interface driver requires
73 that BAR2 is assigned to 0xf6000000 as base address from the PCI IO range:
75 &cp0_pcie0 {
76         ranges = <0x81000000 0x0 0xfb000000 0x0 0xfb000000 0x0 0xf0000
77                 0x82000000 0x0 0xf6000000 0x0 0xf6000000 0x0 0x2000000
78                 0x82000000 0x0 0xf9000000 0x0 0xf9000000 0x0 0x100000>;
79         phys = <&cp0_comphy0 0>;
80         status = "okay";
