   1 * ARM Juno R1 PCIe interface
   2
   3 This PCIe host controller is based on PLDA XpressRICH3-AXI IP
   4 and thus inherits all the common properties defined in plda,xpressrich3-axi.txt
   5 as well as the base properties defined in host-generic-pci.txt.

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