3 * ALSA driver for ICEnsemble VT1724 (Envy24HT)
4 *
5 * Lowlevel functions for AudioTrak Prodigy 192 cards
6 * Supported IEC958 input from optional MI/ODI/O add-on card.
7 *
8 * Specifics (SW, HW):
9 * -------------------
10 * * 49.5MHz crystal
11 * * SPDIF-OUT on the card:
12 * - coax (through isolation transformer)/toslink supplied by
13 * 74HC04 gates - 3 in parallel
14 * - output switched between on-board CD drive dig-out connector
15 * and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled
16 * by GPIO20 (0 = CD dig-out, 1 = SPDTX)
17 * * SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax
18 *
19 * * MI/ODI/O card: AK4114 based, used for iec958 input only
20 * - toslink input -> RX0
21 * - coax input -> RX1
22 * - 4wire protocol:
23 * AK4114 ICE1724
24 * ------------------------------
25 * CDTO (pin 32) -- GPIO11 pin 86
26 * CDTI (pin 33) -- GPIO10 pin 77
27 * CCLK (pin 34) -- GPIO9 pin 76
28 * CSN (pin 35) -- GPIO8 pin 75
29 * - output data Mode 7 (24bit, I2S, slave)
30 * - both MCKO1 and MCKO2 of ak4114 are fed to FPGA, which
31 * outputs master clock to SPMCLKIN of ice1724.
32 * Experimentally I found out that only a combination of
33 * OCKS0=1, OCKS1=1 (128fs, 64fs output) and ice1724 -
34 * VT1724_MT_I2S_MCLK_128X=0 (256fs input) yields correct
35 * sampling rate. That means that the FPGA doubles the
36 * MCK01 rate.
