[Assuming what is really on the board is a tsi109...]

I recommend putting both 109 and 108 in the property, in
that order; that way, if you need to do something special
on the tsi109 implementation (something you might not yet
know about perhaps, maybe a bug; or some extra feature on
the tsi109 device that the driver doesn't handle yet), the
driver has a chance to do that.  If the driver doesn't care
and only uses tsi108 features, it obviously can probe for
tsi108 only and all will be fine as well.
