config SND_SOC_TEGRA210_DMIC
tristate "Tegra210 DMIC module"
help
Config to enable the Digital MIC (DMIC) controller which is used
to interface with Pulse Density Modulation (PDM) input devices.
The DMIC controller implements a converter to convert PDM signals
to Pulse Code Modulation (PCM) signals. This can be viewed as a
PDM receiver.

converts the multi-bit Pulse Code Modulation (PCM) audio input to
oversampled 1-bit Pulse Density Modulation (PDM) output. From the
signal flow perspective DSPK can be viewed as a PDM transmitter
that up-samples the input to the desired sampling rate by
interpolation and then converts the oversampled PCM input to
the desired 1-bit output via Delta Sigma Modulation (DSM).
Say Y or M if you want to add support for Tegra186 DSPK module.

from AHUB must interface through an ADMAIF channel. ADMA channel
sending data to AHUB pairs with an ADMAIF Tx channel, where as
ADMA channel receiving data from AHUB pairs with an ADMAIF Rx
channel. Buffer size is configurable for each ADMAIIF channel.
Say Y or M if you want to add support for Tegra210 ADMAIF module.

Config to enable the Audio Demultiplexer (ADX) which takes an
input stream (up to 16 channels) and demultiplexes it into four
output streams (each of up to 16 channels). A byte RAM helps to
form output frames by any combination of bytes from the input
frame. Its design is identical to that of byte RAM in the AMX
except that the data flow direction is reversed.
