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"; |
|
};
