This codec (don't know STAC9705, STAC9704 or whatever) is audio only
codec, all modem related registers are zeroed. So yes, it is normal.

Just same I guess.

No.

Yes, this CODEC_STRL/CODEC_EN stuff is very unclear for me, so I
used "full set" (CODEC0|CODEC1|MODEM) for begging. Should be clarified
in experimental way.


mainly I'm not about cleanups now. The goal is to hack modem. It looks
for me that right sequence is:

1. Find and initialize modem codec (secondary).
2. Find and hack appropriate DMA channels, initialize modem PCM.
3. Find valid way to access GPIO (for DAA controls like Hook-Off)
4. Chipset detailed cleanups.

Currently we are in (1).
