 * ARM Juno R1 PCIe interface

 This PCIe host controller is based on PLDA XpressRICH3-AXI IP
 and thus inherits all the common properties defined in plda,xpressrich3-axi.txt
 as well as the base properties defined in host-generic-pci.txt.

 Required properties:
  - compatible: "arm,juno-r1-pcie"
  - dma-coherent: The host controller bridges the AXI transactions into PCIe bus
    in a manner that makes the DMA operations to appear coherent to the CPUs.
