Or its parent, or its grandparent, etc.

Domain.  An interrupt nexus is to the interrupt tree
what a node is to the device tree.

s/line/pin/ to agree with PCI terminology.

phandle _of_ the parent node please.

Same thing again.  You missed an underscore, too.

s/required/require/

same thing


Looks good otherwise, thanks.
