* Freescale i.MX6 PCIe interface

This PCIe host controller is based on the Synopsis Designware PCIe IP
and thus inherits all the common properties defined in designware-pcie.txt.

Required properties:
- compatible: "fsl,imx6q-pcie"
- reg: base addresse and length of the pcie controller
- interrupts: A list of interrupt outputs of the controller. Must contain an
  entry for each entry in the interrupt-names property.
- interrupt-names: Must include the following entries:
	- "msi": The interrupt that is asserted when an MSI is received
- clock-names: Must include the following additional entries:
	- "pcie_phy"

Example:

		compatible = "fsl,imx6q-pcie", "snps,dw-pcie";
