[linux-2.6-microblaze.git] / Documentation / devicetree / bindings / pci / axis,artpec6-pcie.txt
1 * Axis ARTPEC-6 PCIe interface
2
3 This PCIe host controller is based on the Synopsys DesignWare PCIe IP
4 and thus inherits all the common properties defined in designware-pcie.txt.
5
6 Required 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 - reg: base addresses and lengths of the PCIe controller (DBI),
10         the PHY controller, and configuration address space.
11 - reg-names: Must include the following entries:
12         - "dbi"
13         - "phy"
14         - "config"
15 - interrupts: A list of interrupt outputs of the controller. Must contain an
16   entry for each entry in the interrupt-names property.
17 - interrupt-names: Must include the following entries:
18         - "msi": The interrupt that is asserted when an MSI is received
19 - axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
20         used to enable and control the Synopsys IP.
