      1Marvell Prestera Switch Chip bindings
      2-------------------------------------
      3
      4Required 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
     11
     12Optional properties:
     13- dfx: phandle reference to the "DFX Server" node
     14
     15Example:
     16
     17switch {
     18	compatible = "simple-bus";
     19	#address-cells = <1>;
     20	#size-cells = <1>;
     21	ranges = <0 MBUS_ID(0x03, 0x00) 0 0x100000>;
     22
     23	packet-processor@0 {
     24		compatible = "marvell,prestera-98dx3236", "marvell,prestera";
     25		reg = <0 0x4000000>;
     26		interrupts = <33>, <34>, <35>;
     27		dfx = <&dfx>;
     28	};
     29};
     30
     31DFX Server bindings
     32-------------------
     33
     34Required 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.
     38
     39Example:
     40
     41dfx-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>;
     47};
     48
     49Marvell Prestera SwitchDev bindings
     50-----------------------------------
     51Optional 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.
     55
     56Example:
     57
     58eeprom_mac_addr: eeprom-mac-addr {
     59       compatible = "eeprom,mac-addr-cell";
     60       status = "okay";
     61
     62       nvmem = <&eeprom_at24>;
     63};
     64
     65prestera {
     66       compatible = "marvell,prestera";
     67       status = "okay";
     68
     69       base-mac-provider = <&eeprom_mac_addr>;
     70};
     71
     72The current implementation of Prestera Switchdev PCI interface driver requires
     73that BAR2 is assigned to 0xf6000000 as base address from the PCI IO range:
     74
     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";
     81};
