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