v3 just adds prerequisites for the existing interrupts_property test, to avoid double checks. Changelog below. =============== The interrupt-map properties can be quite tricky, as they are already hard to read in their source form, and depend on at least two nodes. The first patch adds a separate test for interrupt providers, to avoid redundant warnings for missing properties later. Patch 2/3 is the actual check routine, to verify some features of the map. In particular it should be able to spot missing fields or fields using the wrong number of cells. Most of the fields cannot easily be verified, but at the least the phandle to the interrupt controller and the total number of cells in the property should be valid. It actually find problems in the Linux kernel tree's .dts files. The third patch is more a proof of concept, not sure it should be merged as is, since it deviates from the current output scheme: It adds more output in case a map is considered broken, so the issue can be found much easier. I would be happy with it living on the list for now. Please let me know what you think.
