Currently ALSA dice driver handles a pair of isochronous resources for IEC 61883-1/6 packet streaming. While, according to some documents about ASICs named as 'Dice', several isochronous streams are available. Here, I start to describe ASICs produced under 'Dice' name. * Dice II (designed by wavefront semiconductor, including TCAT's IP) * STD (with limited functionality of DTCP) * CP (with full functionality of DTCP) * TCD2210/2210-E (so-called 'Dice Mini') * TCD2220/2220-E (so-called 'Dice Jr.') * TCD3070-CH (so-called 'Dice III') Some documents are public and we can see hardware design of them. We can find some articles about hardware internal register definitions (not registers exported to IEEE 1394 bus). * DICE II User Guide * http://www.tctechnologies.tc/archive/downloads/dice_ii_user_guide.pdf * 6.1 AVS Audio Receivers * Table 6.1: AVS Audio Receiver Memory Map * ARX1-ARX4 * 6.2 AVS Audio Transmitters * Table 6.2: AVS Audio Transmitter Memory Map * ATX1, ATX2 * TCD22xx User Guide * http://www.tctechnologies.tc/downloads/tcd22xx_user_guide.pdf * 6.1 AVS Audio Receivers * Table 66: AVS Audio Receiver Memory Map * ARX1, ARX2 * 6/2 AVS Audio Transmitters * Table 67: AVS Audio Transmitter Memory Map * ATX1, ATX2 * DICE III * http://www.tctechnologies.tc/downloads/TCD3070-CH.pdf * Dual stream 63 channel transmitter/receiver For Dice II and TCD22xx series, maximum 16 data channels are transferred in an AMDTP packet, while for Dice III, maximum 32 data channels are transferred. According to the design of the series of these ASICs, this commit allows this driver to handle additional set of isochronous resources. For practical reason, two pair of isochronous resources are added. As of this commit, this driver still use a pair of the first isochronous resources.
