I see it with other devices as well. Interrupt numbers in boot log and
interrupt property in device tree are not the same entity, maybe, I am
not sure. I checked it on a running device, so it is nothing wrong,

Well, none. I just looked over the description and as RV panel has
ethernet connectibity, it could help tremendously while developing
(using nfs for file system etc). It could even work out of the box
using if_awg interface, which should match according device tree dump
you posted... but RV Dock has nothing like this, unfortunatelly.
