will you be able to send a v2 with the fixes we discussed in this
thread? No driver changes, just the binding for the new specific
compatible string, and the DT changes.
I tested this on the X96QPro+, and also managed to enable IR operation
on the Avaota board, where it uses the other IP instance (and another
pin).

Please let us know if you can send a new version this week still, to
possibly allow a v7.3 merge. Happy to review that quickly then.
If not, please drop me a note, I can then take care of that.

Cheers,
Andre
