Hrm, interesting. I pulled and update my hg tree. I'll take a look.

Actually, the core code wasn't written specifically for the D965
support. I wrote and submitted support for the 927x code against
the sigmatel reference codec board before these patches for D965
got in. The 927x support was committed 23 Jan 2006, 9227/8/9 codec
support via the 927x patch path was committed 06 July 2006. Those
are the portions I authored. It looks like the D965/9227 specific
support showed up on 22 Aug 2006. All according to the hg logs.

This patch does no such thing. The reason i say "refactor" is that
it properly separates 927x and 9227 codecs. They are different. The
Intel patch just hacked in D965 support for the 9227 using the
927x path. If you look closely, this patch moves all of those 9227-based
D965 systems over to the 9227 table leaving the 927x table with just
the reference board.  This is needed because the pin widgets on the
9227 and 927x differ in some ways including the digital mic pin
widget nids.
