 * Altera PCIe controller
 
 Required properties:
-- compatible : should contain "altr,pcie-root-port-1.0"
+- compatible : should contain "altr,pcie-root-port-1.0" or "altr,pcie-root-port-2.0"
 - reg:         a list of physical base address and length for TXS and CRA.
+               For "altr,pcie-root-port-2.0", additional HIP base address and length.
 - reg-names:   must include the following entries:
                "Txs": TX slave port region
                "Cra": Control register access region
+               "Hip": Hard IP region (if "altr,pcie-root-port-2.0")
 - interrupts:  specifies the interrupt source of the parent interrupt
                controller.  The format of the interrupt specifier depends
                on the parent interrupt controller.
