1* Axis ARTPEC-6 PCIe interface
2
3This PCIe host controller is based on the Synopsys DesignWare PCIe IP
4and thus inherits all the common properties defined in designware-pcie.txt.
5
6Required properties:
7- compatible: "axis,artpec6-pcie", "snps,dw-pcie" for ARTPEC-6 in RC mode;
8	      "axis,artpec6-pcie-ep", "snps,dw-pcie" for ARTPEC-6 in EP mode;
9	      "axis,artpec7-pcie", "snps,dw-pcie" for ARTPEC-7 in RC mode;
10	      "axis,artpec7-pcie-ep", "snps,dw-pcie" for ARTPEC-7 in EP mode;
11- reg: base addresses and lengths of the PCIe controller (DBI),
12	the PHY controller, and configuration address space.
13- reg-names: Must include the following entries:
14	- "dbi"
15	- "phy"
16	- "config"
17- interrupts: A list of interrupt outputs of the controller. Must contain an
18  entry for each entry in the interrupt-names property.
19- interrupt-names: Must include the following entries:
20	- "msi": The interrupt that is asserted when an MSI is received
21- axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
22	used to enable and control the Synopsys IP.
