If there a series about to be merged I can rebase my series on it. Else
I propose to keep it and convert the family check to ops when you will
send the series for it.

I confirm that 6141 and 6341 are called Topaz. Actually I can add the
support for the 6141 too, it is just a matter of adding an ID and maybe
removing some ops as 6141 is a subset of 6341.
