+ * 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
+ * ------------------------------
+ * CDTO (pin 32) -- GPIO11 pin 86
+ * CDTI (pin 33) -- GPIO10 pin 77
+ * CCLK (pin 34) -- GPIO9 pin 76
+ * CSN (pin 35) -- GPIO8 pin 75
+ * - output data Mode 7 (24bit, I2S, slave)
+ * - both MCKO1 and MCKO2 of ak4114 are fed to FPGA, which
+ * outputs master clock to SPMCLKIN of ice1724.
+ * Experimentally I found out that only a combination of
+ * OCKS0=1, OCKS1=1 (128fs, 64fs output) and ice1724 -
+ * VT1724_MT_I2S_MCLK_128X=0 (256fs input) yields correct
+ * sampling rate. That means that the FPGA doubles the
+ * MCK01 rate.
