The binding didn't change, but bugs were fixed in the parsing code so
that what was common practice (but wrong) in 2.6.23 doesn't work anymore.
Your tsi108 node only provides a ranges translation for its own
registers, but you have a PCI child node with ranges outside of that.
It's a bit awkward, but what we currently tend to do is move the PCI
node out to the root level (make sure to change the reg property to be
the full address rather than the tsi108 offset).
