Merge series "Extend AHUB audio support for Tegra210 and later" from Sameer Pujar <spujar@nvidia.com>:

Earlier as part of series [0], support for ADMAIF and I/O modules (such
as I2S, DMIC and DSPK) was added. This series aims at exposing some of
the AHUB internal modules (listed below), which can be used for audio
pre or post processing.

  * SFC (Sampling Frequency Converter)
  * MVC (Master Volume Control)
  * AMX (Audio Multiplexer)
  * ADX (Audio Demultiplexer)
  * Mixer

These modules can be plugged into audio paths and relevant processing
can be done. The MUX routes are extended to allow add or remove above
modules in the path via mixer controls. This is similar to how specific
ADMAIF channels are connected to relevant I/O module instances at the
moment.

Some of these modules can alter PCM parameters. Consider example of
resampler (44.1 -> 48 kHz) in the path.

  aplay(44.1 kHz) -> ADMAIF -> SFC -> (48 kHz) I2S -> (48kHz) Codec

The modules following SFC should be using converted sample rate and DAIs
need to be configured accordingly. The audio-graph driver provides a
mechanism to fixup the new parameters which can be specified in DT for a
given DAI. Then core uses these new values via fixup callback and then
pass it to respective DAIs hw_param() callback. The "convert-rate",
described in [1], property can be used when there is rate conversion in
the audio path. Similarly "convert-channels" can be used when there is
channel conversion in the path. There is no "convert-xxx" property for
sample size conversions. It can be added if necessary.

Changelog
=========

v1 -> v2
--------
 * Put comments for soft reset application in the drivers.
 * Split out mute/volume control logic in put() calls of MVC driver and
   use separate callbacks for the respective kcontrols.
 * Update kcontrol put() callback in MVC driver to return 1 whenever
   there is change. Similar change is done in other drivers too.
 * Use name-prefix.yaml reference for the driver documentation now.
 * Add sound-name-prefix pattern for MIXER driver and use prefix
   accordingly in DT.
