    ALSA: dice: add support for Solid State Logic Duende Classic/Mini · b2e9e1c8
    Takashi Sakamoto authored
    Duende Classic was produced by Solid State Logic in 2006, as a
    first model of Duende DSP series. The following model, Duende Mini
    was produced in 2008. They are designed to receive isochronous
    packets for PCM frames via IEEE 1394 bus, perform signal processing by
    downloaded program, then transfer isochronous packets for converted
    PCM frames.
    
    These two models includes the same embedded board, consists of several
    ICs below:
     - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus
     - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer
     - Altera MAX 3000A CPLD for programs
     - Analog devices, SHARC ADSP-21363 for signal processing (4 chips)
    
    This commit adds support for the two models to ALSA dice driver. Like
    support for the other devices, packet streaming is just available.
    Userspace applications should be developed if full features became
    available; e.g. program uploader and parameter controller.
