   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.
