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 = ; }; 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"; };
