 403  * AHUB: Audio Hub; a cross-bar switch between the audio devices: DMA FIFOs,
 404  *       I2S controllers, SPDIF controllers, and DAMs.
 405  * XBAR: The core cross-bar component of the AHUB.
 406  * CIF:  Client Interface; the HW module connecting an audio device to the
 407  *       XBAR.
 408  * DAM:  Digital Audio Mixer: A HW module that mixes multiple audio streams,
 409  *       possibly including sample-rate conversion.
 410  *
 411  * Each TX CIF transmits data into the XBAR. Each RX CIF can receive audio
 412  * transmitted by a particular TX CIF.
 413  *
 414  * This driver is currently very simplistic; many HW features are not
 415  * exposed; DAMs are not supported, only 16-bit stereo audio is supported,
 416  * etc.
