Yes, the target is TSB82AA2. The OHCI1.2 is listed as reference in its
datasheet(1.3 Related Documents). It seems that there are some
extenstions(*1) in stream packet format in OHCI1.1+/1.2 rather than
registers. As you know, OHCI packet format is somewhat different from
1394 packet format.

Do you have any information about difference between 1.1 and 1.1+ or
1.2?

(*) I observed some strange behavior if we don't fill reserved field
with zero.
