Remove undocumented and unneeded ti,use-internal-reg from the example as
it was an artifact from initial development. The code does not query
for this property and as the document indicates if areg-supply is
undefined then the internal regulator is used.

The TLV320ADCX140 are multichannel (4-ch analog recording or 8-ch digital
|
||
PDM microphones recording), high-performance audio, analog-to-digital
|
||
converter (ADC) with analog inputs supporting up to 2V RMS. The TLV320ADCX140
|
||
family supports line and microphone Inputs, and offers a programmable
|
||
microphone bias or supply voltage generation.
