This patch changes the Intel HD Audio device driver to include
the support of HD Audio device embedded in ATI south bridge
IXP450. Because the design of ATI chipset follows intel HD Audio
specification 1.0, the programming method is the same as that
of intel HD Audio device exception one minor change which requires
to enable snoop for DMA transport. There are 3 changes that have been
made to hda_intel.c file.
1. Added device ID for ATI HD Audio device;
2. Increase maximum CODEC supported to 4;
3. Enable snoop during the driver initialization.

Patch by C.L. Tien <cltien@cmedia.com.tw>:
The patch makes cm9880 to choose multi-channel jacks automatically.
1. I found the current code has basic_init, which already includes
necessary controls for 6-stack initialization, so I don't need
another model.
2. I add a new model 'auto' to let the driver find a. if there are
option real panel/front panel, b. the jacks to be used for multichannel.
Because the jack color are based on MS's channel sequence, so the 'auto'
model will pick the same jacks for multichannel MS uses. I did this to
hope to minimize users questions. These code can also be applied to other
codecs but I don't have any to test.

This patch hacks the current PowerMac Alsa driver to add some basic support
of analog sound output to some desktop G5s. It has severe limitations
though:
- Only 44100Khz 16 bits
- Only work on G5 models using a TAS3004 analog code, that is early
single CPU desktops and all dual CPU desktops at this date, but none
of the more recent ones like iMac G5.
- It does analog only, no digital/SPDIF support at all, no native
AC3 support
Better support would require a complete rewrite of the driver (which I am
working on, but don't hold your breath), to properly support the diversity
of apple sound HW setup, including dual codecs, several i2s busses, all the
new codecs used in the new machines, proper clock switching with digital,
etc etc etc...
This patch applies on top of the other PowerMac sound patches I posted in
the past couple of days (new powerbook support and sleep fixes).
Note: This is a FAQ entry for PowerMac sound support with TI codecs: They
have a feature called "DRC" which is automatically enabled for the internal
speaker (at least when auto mute control is enabled) which will cause your
sound to fade out to nothing after half a second of playback if you don't
set a proper "DRC Range" in the mixer. So if you have a problem like that,
check alsamixer and raise your DRC Range to something reasonable.
Note2: This patch will also add auto-mute of the speaker when line-out jack
is used on some earlier desktop G4s (and on the G5) in addition to the
headphone jack. If that behaviour isn't what you want, just disable
auto-muting and use the manual mute controls in alsamixer.

models. The Mac Mini is _NOT_ yet supported by this patch (soon soon ...).
The G5s (iMac or Desktop) will need the rewritten sound driver on which
I'm working on (I _might_ get a hack for analog only on some G5s on the
current driver, but no promise).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
