+ * CIF:  Client Interface; the HW module connecting an audio device to the
+ *       XBAR.
+ * DAM:  Digital Audio Mixer: A HW module that mixes multiple audio streams,
+ *       possibly including sample-rate conversion.
+ *
+ * Each TX CIF transmits data into the XBAR. Each RX CIF can receive audio
+ * transmitted by a particular TX CIF.
+ *
+ * This driver is currently very simplistic; many HW features are not
+ * exposed; DAMs are not supported, only 16-bit stereo audio is supported,
+ * etc.
