-* Altera PCIe controller
-
-Required properties:
-- 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.
-- device_type:	must be "pci"
-- #address-cells:	set to <3>
-- #size-cells:		set to <2>
-- #interrupt-cells:	set to <1>
-- ranges:	describes the translation of addresses for root ports and
-		standard PCI regions.
-- interrupt-map-mask and interrupt-map: standard PCI properties to define the
-		mapping of the PCIe interface to interrupt numbers.
-
-Optional properties:
-- msi-parent:	Link to the hardware entity that serves as the MSI controller
-		for this PCIe controller.
-- bus-range:	PCI bus numbers covered
