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"
8- reg: base addresses and lengths of the PCIe controller (DBI),
9	the phy controller, and configuration address space.
10- reg-names: Must include the following entries:
11	- "dbi"
12	- "phy"
13	- "config"
14- interrupts: A list of interrupt outputs of the controller. Must contain an
15  entry for each entry in the interrupt-names property.
16- interrupt-names: Must include the following entries:
17	- "msi": The interrupt that is asserted when an MSI is received
18- axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
19	used to enable and control the Synopsys IP.
