Glad to hear it was only just missed, hope it helps making these patches
truly a step-up from the downstream driver it was based on :)

I would have submitted them in parallel straight away and link them
together, so that review can commence immediately on both.  Perhaps then
the XML could be merged up-front so that these patches don't need to
block on a stable commit-hash to regenerate the headers from?
In this case I/we would have immediately requested to move all the
register constants and offsets (even those that currently have an
unknown meaning) into the XML, and we can later fill in the details.
