If you can leave the Logic PD Torpedo board alone and don't remove the
legacy st driver for now, go ahead and migrate the others.  I know
what you proposed 'should' work on my board, but I don't know why it
doesn't.  In fact other boards I maintain use your method, but it just
doesn't work on the Torpedo and I don't know why.  (it's not for lack
of trying)
