* Axis ARTPEC-6 PCIe interface
|
||
|
|
|
||
|
|
This PCIe host controller is based on the Synopsys DesignWare PCIe IP
|
||
|
|
and thus inherits all the common properties defined in designware-pcie.txt.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "axis,artpec6-pcie", "snps,dw-pcie"
|
||
|
|
- reg: base addresses and lengths of the PCIe controller (DBI),
|
||
|
|
the PHY controller, and configuration address space.
|
||
|
|
- reg-names: Must include the following entries:
|
||
|
|
- "dbi"
|
||
|
|
- "phy"
|
||
|
|
- "config"
|
||
|
|
- interrupts: A list of interrupt outputs of the controller. Must contain an
|
||
|
|
entry for each entry in the interrupt-names property.
|
||
|
|
- interrupt-names: Must include the following entries:
|
||
|
|
- "msi": The interrupt that is asserted when an MSI is received
|
||
|
|
- axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
|
||
|
|
used to enable and control the Synopsys IP.
|
||
|
|
|
||
|
