Audio and music units of RME Fireface series use its own protocol for isochronous packets to transfer data. This protocol requires ALSA IEC 61883-1/6 engine to have alternative functions. This commit is a preparation for the protocol. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
