+ * This module support maximum 2 pairs of tx/rx isochronous streams for
+ * our convinience.
+ *
+ * In documents for ASICs called with a name of 'DICE':
+ *  - ASIC for DICE II:
+ *   - Maximum 2 tx and 4 rx are supported.
+ *   - A packet supports maximum 16 data channels.
+ *  - TCD2210/2210-E (so-called 'Dice Mini'):
+ *   - Maximum 2 tx and 2 rx are supported.
+ *   - A packet supports maximum 16 data channels.
+ *  - TCD2220/2220-E (so-called 'Dice Jr.')
+ *   - 2 tx and 2 rx are supported.
+ *   - A packet supports maximum 16 data channels.
+ *  - TCD3070-CH (so-called 'Dice III')
+ *   - Maximum 2 tx and 2 rx are supported.
+ *   - A packet supports maximum 32 data channels.
+ *
+ * For the above, MIDI conformant data channel is just on the first isochronous
+ * stream.
