+Marvell Prestera SwitchDev bindings
+-----------------------------------
+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
