The child node name in use by .dts files and the driver is "legacy-interrupt-controller", not "interrupt-controller".After your change commit bcd7ec2cd720 were merged, it was a long time before I realized I needed to fix it. "interrupt-controller" is included in the list of Generic Names Recommendation. Would it be better to apply (i.e. restore) this, or fix the PCI driver and .dts?
It's an ABI. So we are stuck with it or have to support both names in the driver forever (and backport the driver change). Rob
