Good catch! I believe this is another copy-paste error when creating
base dtsi based on some vendor source (or perhaps an error carried over
from an earlier version).
The vendor devicetree I have access to also has 811 here, which matches
the pattern for usb_0 (dwc3 interrupt + 1).
Do you mind if I fold a fix for that into a v2 of this patch?
Thanks for reviewing!
