In Fireface series, registration of higher 4 bytes of destination address for asynchronous transaction of MIDI messages is done by a write transaction to model-specific register. On the other hand, registration of lower 4 bytes of the address is selectable from 4 options. A register for this registration includes the other purpose options such as input attenuation. Thus this driver expects userspace applications to configure the register. Actual behaviour for the asynchronous transaction is different depending on protocols. In former protocol, destination offset of each transaction is the same as the registered address even if it is block request. In latter models, destination offset of each transaction is the offset of previous transaction plus 4 byte and the transaction is quadlet request. This commit cleanups comments about the above mechanism. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
