| * 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 snps,dw-pcie.yaml. |
| |
| Required properties: |
| - compatible: "axis,artpec6-pcie", "snps,dw-pcie" for ARTPEC-6 in RC mode; |
| "axis,artpec6-pcie-ep", "snps,dw-pcie" for ARTPEC-6 in EP mode; |
| "axis,artpec7-pcie", "snps,dw-pcie" for ARTPEC-7 in RC mode; |
| "axis,artpec7-pcie-ep", "snps,dw-pcie" for ARTPEC-7 in EP mode; |
| - 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. |
