convert the Texas Instruments PCM186x Universal audio ADC bindings to DT schema. The PCM186x codec provides a single digital audio interface. Therefore this binding adds a reference to dai-common.yaml and defines '#sound-dai-cells = 0".

|
The Texas Instruments PCM186x family are multi-channel audio ADCs
|
|
that support both I2C and SPI control interfaces, selected by
|
|
pin strapping. These devices include on-chip programmable gain
|
|
amplifiers and support differential or single-ended analog inputs.
|
|
|
|
CODEC input pins:
|
|
* VINL1
|
|
* VINR1
|
|
* VINL2
|
|
* VINR2
|
|
* VINL3
|
|
* VINR3
|
|
* VINL4
|
|
* VINR4
|
|
|
|
The pins can be used in referring sound node's audio-routing property.
