* 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:
|
|
|
|

|
|
