0001 * Axis ARTPEC-6 PCIe interface
0002
0003 This PCIe host controller is based on the Synopsys DesignWare PCIe IP
0004 and thus inherits all the common properties defined in snps,dw-pcie.yaml.
0005
0006 Required properties:
0007 - compatible: "axis,artpec6-pcie", "snps,dw-pcie" for ARTPEC-6 in RC mode;
0008 "axis,artpec6-pcie-ep", "snps,dw-pcie" for ARTPEC-6 in EP mode;
0009 "axis,artpec7-pcie", "snps,dw-pcie" for ARTPEC-7 in RC mode;
0010 "axis,artpec7-pcie-ep", "snps,dw-pcie" for ARTPEC-7 in EP mode;
0011 - reg: base addresses and lengths of the PCIe controller (DBI),
0012 the PHY controller, and configuration address space.
0013 - reg-names: Must include the following entries:
0014 - "dbi"
0015 - "phy"
0016 - "config"
0017 - interrupts: A list of interrupt outputs of the controller. Must contain an
0018 entry for each entry in the interrupt-names property.
0019 - interrupt-names: Must include the following entries:
0020 - "msi": The interrupt that is asserted when an MSI is received
0021 - axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
0022 used to enable and control the Synopsys IP.
