-* Xilinx AXI PCIe Root Port Bridge DT description
-
-Required properties:
-- #address-cells: Address representation for root ports, set to <3>
-- #size-cells: Size representation for root ports, set to <2>
-- #interrupt-cells: specifies the number of cells needed to encode an
- interrupt source. The value must be 1.
-- compatible: Should contain "xlnx,axi-pcie-host-1.00.a"
-- reg: Should contain AXI PCIe registers location and length
-- device_type: must be "pci"
-- interrupts: Should contain AXI PCIe interrupt
-- interrupt-map-mask,
- interrupt-map: standard PCI properties to define the mapping of the
- PCI interface to interrupt numbers.
-- ranges: ranges for the PCI memory regions (I/O space region is not
- supported by hardware)
- Please refer to the standard PCI bus binding document for a more
- detailed explanation
-
-Optional properties for Zynq/Microblaze:
-- bus-range: PCI bus numbers covered
-
-Interrupt controller child node
-+++++++++++++++++++++++++++++++
-Required properties:
-- interrupt-controller: identifies the node as an interrupt controller
-- #address-cells: specifies the number of cells needed to encode an
- address. The value must be 0.
-- #interrupt-cells: specifies the number of cells needed to encode an
- interrupt source. The value must be 1.
-
-NOTE:
-The core provides a single interrupt for both INTx/MSI messages. So,
-created a interrupt controller node to support 'interrupt-map' DT
-functionality. The driver will create an IRQ domain for this map, decode
-the four INTx interrupts in ISR and route them to this domain.
