[PATCH] dt-bindings: PCI: socionext,uniphier-pcie: Add missing child interrupt controller

Rob Herring
2022-05-25T21:01:32Z

The Socionext interrupt controller internal to the the PCI block isn't
documented which causes warnings when unevaluatedProperties check is
also fixed. Add the 'interrupt-controller' child node and properties and
fixup the example so that interrupt properties can be parsed.
