Subject: [PATCH 24/39] fireworks: Add PCM interface
Date: Wed,  5 Mar 2014 19:48:12 +0900
Message-ID: <1394016507-15761-25-git-send-email-o-takashi@sakamocchi.jp> (raw)
In-Reply-To: <1394016507-15761-1-git-send-email-o-takashi@sakamocchi.jp>

This commit adds a functionality to capture/playback PCM samples.

When AMDTP stream is already running for PCM or the source of clock is not
internal, available sampling rate is limited at current one.
