 * FPGA (aka HANA):
 * ---------------
 *    * provides all (?) physical inputs and outputs of the card
 *          (ADC, DAC, SPDIF I/O, ADAT I/O, etc.)
 *    * provides clock signal for the card and Alice2
 *    * two crystals - for 44.1kHz and 48kHz multiples
 *    * provides internal routing of signal sources to signal destinations
 *    * inputs/outputs to Alice2 - see above
 *
 * Current status of the driver:
 * ----------------------------
 *    * only 44.1/48kHz supported (the MS Win driver supports up to 192 kHz)
 *    * PCM device nb. 2:
 *          16 x 16-bit playback - snd_emu10k1_fx8010_playback_ops
 *          16 x 32-bit capture - snd_emu10k1_capture_efx_ops
