[ALSA] ice1724 - Functioning support for Prodigy 192
Fixes: -------- * correct card specific ice1724 initialization * working IEC958 output of the card * renamed capture controls New features: ------------------ * analog input switch (line-in/mic) * optional ak4114 based MI/ODI/O card detection & support: IEC958 input, digital input switch (toslink/coax) Unresolved issues ----------------------- * Analog and digital input enums are listed on playback panel of alsamixer, I do not know how to push them onto the capture one.

* ALSA driver for ICEnsemble VT1724 (Envy24HT)
|

*
|

* Lowlevel functions for AudioTrak Prodigy 192 cards
|
||||
* Supported IEC958 input from optional MI/ODI/O add-on card.

*
|
||||
* Specifics (SW, HW):
|
||||
* -------------------
|
||||
* * 49.5MHz crystal
|
||||
* * SPDIF-OUT on the card:
|
||||
* - coax (through isolation transformer)/toslink supplied by
|
||||
* 74HC04 gates - 3 in parallel
|
||||
* - output switched between on-board CD drive dig-out connector
|
||||
* and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled
|
||||
* by GPIO20 (0 = CD dig-out, 1 = SPDTX)
|
||||
* * SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax
|
||||
*
|
||||
* * MI/ODI/O card: AK4114 based, used for iec958 input only
|
||||
* - toslink input -> RX0
|
||||
* - coax input -> RX1
|
||||
* - 4wire protocol:
|
||||
* AK4114 ICE1724
