This property allows to select the PCM data input channel that is routed to the speaker audio processing bypass path. The driver already implements this property. While at it, fix the default value for adi,imon-slot-no.

|
|
The MAX98396 is a mono Class-DG speaker amplifier with I/V sense.
|
|
The device provides a PCM interface for audio data and a standard
|
|
I2C interface for control data communication.
|
|
The MAX98397 is a variant of MAX98396 with wide input supply range.

For cases where a single combined channel for the I/V sense data

is not sufficient, the device can also be configured to share

a single data output channel on alternating frames.
|
|
In this configuration, the current and voltage data will be frame
|
|
interleaved on a single output channel.
