+The sub-functions of CPCAP get their own node with their own compatible values,
+which are described in the following files:

+The only exception is the audio codec. Instead of a compatible value its
+node must be named "audio-codec".

+Required properties for the audio-codec subnode:

+- #sound-dai-cells = <1>;

+The audio-codec provides two DAIs. The first one is connected to the
+Stereo HiFi DAC and the second one is connected to the Voice DAC.
