Maple has only one as well, that's the point :-)
It gets the ISU address from that awful platform-open-pic
property currently, hardcoding it like you did for PA6T is
just fine though.  It simplifies the code quite a bit and
doesn't depend on this undocumented (and badly defined no
matter what) device tree property.
