Rosen reported strange dtc warnings that had their origin in an upstream patch to 5.8-rc1. Upon further digging this revealed an ongoing thread [0] discussing the topic: > [...]I don't think we need a bunch of warning fix patches to add > these everywhere. Also, the need for #address-cells pretty much makes > no sense on any modern system. It is a relic from days when the bus > (address) topology and interrupt topology were related. and later on: > So really, we only need to be checking for #address-cells in nodes > with interrupt-map. This patch backports just the patch which removed the warning message (this is from the upstream dtc project [1] - but not the kernel). the patch does not add the checking of the #address-cells in nodes with interrupt-map.

Subject: [PATCH] checks: Drop interrupt provider '#address-cells' check
|
|
|
|
'#address-cells' is only needed when parsing 'interrupt-map' properties, so
|
|
remove it from the common interrupt-provider test.
