cf78ee2ccc [ALSA] ice1712 - Set mpu401 info flags from _card_info
To permit use, in ice1712, of the mpu401 info flags recently added to
mpu401_uart, adds info_flags in snd_ice1712_card_info so that additional
flags can be set, if desired.  'MPU401_INFO_INTEGRATED' is always set with
the ice1712.  The flags are passed on to snd_mpu401_uart_new().
_INFO_OUTPUT is set for DMX6fire mpu2.

3bef229e4f [ALSA] ice1712 - Provides specified midi port names instead of defaults
Patch provides for the ice1712 card driver to overwrite the midi port name
string given by default in mpu401_uart, with one specified in
snd_ice1712_card_info.

af9b70ac00 [ALSA] Add Aux input switch control for Aureon Universe
This patch adds a mixer control which allows the user to switch the Aux
playback between the internal Aux jack, Wavetable, and Rear Line-In on
Aureon Universe cards.

For switching, a PCA9554 (8-line GPIO with I2C interface) and a 74HC4052
(dual 4-way mux/demux) are used.  Output 0 and 1 of the PCA9554 are
connected to the select pins of the 74HC4052. The I2C interface of the
PCA9554 is connected to the card's internal SPI bus which is also used
to control the WM8770 and CS8415. SPI and I2C on the same lines...

To communicate with the PCA9554 the WM8770 and CS8415 are disabled and
an I2C Stop Condition is generated before the Start Condition (needed
for synchronisation because other SPI traffic appear to confuse the
PCA9554). Then a normal I2C data transfer takes place.  Programming must
be done ridiculously slow; in theory, 4.7us is the minimum delay time
for normal-speed I2C according to the datasheet, but even with 10us
switching was unreliable.  The Windows driver from Terratec does the
programming very slowly, too (checked with an oscilloscope).

531af46279 [ALSA] ice1712 - disable unused ADCs & DACs on DMX6fire
Modules: ICE1712 driver

Change the value written to hardware configuration register of envy24 chip
in the case of Terratec DMX6fire to restrict the active ADCs & DACs to 6.

Also add the dxr_enable module option to eventually leave the old behaviour
when user requests.

62932df8fb [ALSA] semaphore -> mutex (PCI part)
Semaphore to mutex conversion.

The conversion was generated via scripts, and the result was validated
automatically via a script as well.

aed058e871 [ALSA] Provides preliminary support for the Terratec Phase 28 card
ICE1712 driver
Provides preliminary support for the Terratec Phase 28 card.
Not extensively tested and probably buggy, but it seems to work.

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!
