+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>;
