/* * 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.
