   1 * Freescale i.MX6 PCIe interface
   2
   3 This PCIe host controller is based on the Synopsis Designware PCIe IP
   4 and thus inherits all the common properties defined in designware-pcie.txt.
   5
   6 Required properties:
   7 - compatible: "fsl,imx6q-pcie"
   8 - reg: base addresse and length of the pcie controller
   9 - interrupts: A list of interrupt outputs of the controller. Must contain an
  10   entry for each entry in the interrupt-names property.
  11 - interrupt-names: Must include the following entries:
  12         - "msi": The interrupt that is asserted when an MSI is received
  13 - clock-names: Must include the following additional entries:
  14         - "pcie_phy"
