Another round of wack-a-mole. The json-schema default is additional unknown properties are allowed, but for DT all properties should be defined.

|
description: |
|
|
The Digital Speaker Controller (DSPK) can be viewed as a Pulse
|
|
Density Modulation (PDM) transmitter that up-samples the input to
|
|
the desired sampling rate by interpolation and then converts the
|
|
over sampled Pulse Code Modulation (PCM) input to the desired 1-bit
|
|
output via Delta Sigma Modulation (DSM).

Used as prefix for sink/source names of the component. Must be a

unique string among multiple instances of the same component.

The name can be "DSPK1" or "DSPKx", where x depends on the maximum
|
|
available instances on a Tegra SoC.
