+description: |
+  The TLV320ADCX140 are multichannel (4-ch analog recording or 8-ch digital
+  PDM microphones recording), high-performance audio, analog-to-digital
+  converter (ADC) with analog inputs supporting up to 2V RMS. The TLV320ADCX140
+  family supports line and  microphone Inputs, and offers a programmable
+  microphone bias or supply voltage generation.

 dai names ending with "Playback" and "Capture" respectively as dapm core
 will link and power those dais based on the name.
 
-Note that in current device tree there is no way to mark a dai_link
-as codec to codec. However, it may change in future.
+A dai_link in a "simple-audio-card" will automatically be detected as
+codec to codec when all DAIs on the link belong to codec components.
+The dai_link will be initialized with the subset of stream parameters
+(channels, format, sample rate) supported by all DAIs on the link. Since
+there is no way to provide these parameters in the device tree, this is
+mostly useful for communication with simple fixed-function codecs, such
+as a Bluetooth controller or cellular modem.
