 *	  to 2 x 16-bit, using internal DSP instructions
 * 	* slave mode, clock supplied by HANA
 * 	* linked to HANA using:

 * 		16 x EMU32 input channels
 * 		(?) x I2S I/O channels (?)
 *
 * 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
