Update the entries in the interrupt-map field to have the correct number of address cells for the interrupt parent. Signed-off-by: Matthew Gerlach Reviewed-by: Conor Dooley --- v8: - Precisely constrain the number of items for reg and reg-names properties. Constrain maxItems to 2 for altr,pcie-root-port-1.0. Constrain minItems to 3 for altr,pcie-root-port-2.0. v7: - Keep original example dts, but fix warnings of interrupt-map field. v6: - Fix dt_binding_check warnings by creating interrupt-controller subnode and fixing interrupt-map. - Updated filename in MAINTAINERS. v5: - add interrupt-controller #interrupt-cells to required field - don't touch original example dts v4: - reorder reg-names to match original binding - move reg and reg-names to top level with limits. v3: - Added years to copyright - Correct order in file of allOf and unevaluatedProperties - remove items: in compatible field - fix reg and reg-names constraints - replace deprecated pci-bus.yaml with pci-host-bridge.yaml - fix entries in ranges property - remove device_type from required v2: - Move allOf: to bottom of file, just like example-schema is showing - add constraint for reg and reg-names - remove unneeded device_type - drop #address-cells and #size-cells - change minItems to maxItems for interrupts: - change msi-parent to just "msi-parent: true" - cleaned up required: - make subject consistent with other commits coverting to YAML - s/overt/onvert/g v8 fix --- .../devicetree/bindings/pci/altera-pcie.txt | 50 -------- .../bindings/pci/altr,pcie-root-port.yaml | 114 ++++++++++++++++++ MAINTAINERS | 2 +- 3 files changed, 115 insertions(+), 51 deletions(-) delete mode 100644 Documentation/devicetree/bindings/pci/altera-pcie.txt create mode 100644 Documentation/devicetree/bindings/pci/altr,pcie-root-port.yaml diff --git a/Documentation/devicetree/bindings/pci/altera-pcie.txt b/Documentation/devicetree/bindings/pci/altera-pcie.txt deleted file mode 100644 index 816b244a221e..000000000000 --- a/Documentation/devicetree/bindings/pci/altera-pcie.txt +++ /dev/null @@ -1,50 +0,0 @@ -* Altera PCIe controller - -Required properties: -- compatible : should contain "altr,pcie-root-port-1.0" or "altr,pcie-root-port-2.0" -- reg: a list of physical base address and length for TXS and CRA. - For "altr,pcie-root-port-2.0", additional HIP base address and length. -- reg-names: must include the following entries: - "Txs": TX slave port region - "Cra": Control register access region - "Hip": Hard IP region (if "altr,pcie-root-port-2.0") -- interrupts: specifies the interrupt source of the parent interrupt - controller.
