I suppose this is an ABI break, but the patch just makes the binding match the example and intent. Feels like of all the patches doing the unevaluatedProperty additions, this one is the most deserving of a fixes tag, since the original binding just seems to be completely wrong?

It also matches what the in tree users do, so not an ABI break. I imagine the .txt binding just listed out properties and the conversion carried that over. > Feels like of all the patches doing the > unevaluatedProperty additions, this one is the most deserving of a fixes > tag, since the original binding just seems to be completely wrong? Yes, though the example fix is a dependency, so probably not worth backporting. Fixes: 905b986d099c ("dt-bindings: pci: Convert iProc PCIe to YAML") Rob

The 'msi' child node schema is missing constraints on additional properties. It turns out it is incomplete and properties for it are documented in the parent node by mistake. Move the reference to msi-controller.yaml and the custom properties to the 'msi' node. Adding 'unevaluatedProperties' ensures all the properties in the 'msi' node are documented. With the schema corrected, a minimal interrupt controller node is needed to properly decode the interrupt properties since the example has multiple interrupt parents.
