/*
* 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.
