13  The Texas Instruments PCM186x family are multi-channel audio ADCs
14  that support both I2C and SPI control interfaces, selected by
15  pin strapping. These devices include on-chip programmable gain
16  amplifiers and support differential or single-ended analog inputs.
17
18  CODEC input pins:
19    * VINL1
20    * VINR1
21    * VINL2
22    * VINR2
23    * VINL3
24    * VINR3
25    * VINL4
26    * VINR4
27
28  The pins can be used in referring sound node's audio-routing property.
