Niklas Cassel3f3f67c2016-05-09 13:48:27 +02001* 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:
Niklas Casseldff9cba2017-12-20 00:29:34 +01007- 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;
Niklas Cassel3f3f67c2016-05-09 13:48:27 +02009- reg: base addresses and lengths of the PCIe controller (DBI),
Bjorn Helgaas96291d52017-09-01 16:35:50 -050010 the PHY controller, and configuration address space.
Niklas Cassel3f3f67c2016-05-09 13:48:27 +020011- 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.
