* EMU-1010 - details found out from this driver, official MS Win drivers,
* testing the card:
*
* Audigy2 (aka Alice2):
* ---------------------
* * communication over PCI
* * conversion of 32-bit data coming over EMU32 links from HANA FPGA
* to 2 x 16-bit, using internal DSP instructions
* * slave mode, clock supplied by HANA
* * linked to HANA using:
* 32 x 32-bit serial EMU32 output channels
* 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
* 16 x 32-bit capture - snd_emu10k1_capture_efx_ops
