Support new nvidia,fixed-parent-rate device-tree property which instructs
I2S that board wants parent clock rate to stay at a fixed rate. This allows
to play audio over S/PDIF and I2S simultaneously. The root of the problem
is that audio components on Tegra share the same audio PLL, and thus, only
a subset of rates can be supported if we want to play audio simultaneously.
Filter out audio rates that don't match parent clock rate if device-tree
has the nvidia,fixed-parent-rate property.

SPDIF and other SoC components share audio PLL on Tegra, thus only one
component may set the desired base clock rate. This creates problem for
HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock
doesn't exactly match standard audio rate since some receivers may reject
audio in that case. Filter out audio rates which SPDIF output can't
support, assuming that other components won't change rate at runtime.

The DMA resource is never set up anywhere, and passing this as slave_id
has not been the proper procedure in a long time.
As a preparation for removing all slave_id references from the ALSA code,
remove this one.
According to Dmitry Osipenko, this driver has never been used and
the mechanism for configuring DMA would not work as it is implemented,
so this part will get rewritten when the driver gets put into use
again in the future.

The MVC module has a per channel control bit, based on which it decides
to apply channel specific volume/mute settings. When per channel control
bit is enabled (which is the default HW configuration), all MVC channel
volume/mute can be independently controlled. If the control is disabled,
channel-0 volume/mute setting is applied by HW to all remaining channels.
Thus add support to leverage this HW feature by exposing master controls
for volume/mute.
With this, now there are per channel and master volume/mute controls.
Users need to just use controls which are suitable for their applications.
The per channel control enable/disable is mananged in driver and hidden
from users, so that they need to just worry about respective volume/mute
controls.

The Audio Demultiplexer (ADX) block takes an input stream with up to
16 channels and demultiplexes it into four output streams of up to 16
channels each. 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.
This patch registers ADX driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes ADX interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-adx"
compatible binding.

The Audio Multiplexer (AMX) block can multiplex up to four input streams
each of which can have maximum 16 channels and generate an output stream
with maximum 16 channels. A byte RAM helps to form an output frame by
any combination of bytes from the input frames.
This patch registers AMX driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver

in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-amx" for
Tegra210 and Tegra186. For Tegra194 and later, "nvidia,tegra194-amx" can
be used.

The Sampling Frequency Converter (SFC) converts the sampling frequency
of the input signal from one frequency to another. It supports sampling
frequency conversions of streams of up to two channels (stereo).
This patch registers SFC driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes SFC interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-sfc"
compatible binding.

The Master Volume Control (MVC) provides gain or attenuation to a digital
signal path. It can be used in input or output signal path for per-stream
volume control or it can be used as master volume control. The MVC block
has one input and one output. The input digital stream can be mono or
multi-channel (up to 7.1 channels) stream. An independent mute control is
also included in the MVC block.
This patch registers MVC driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes MVC interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-mvc"
compatible binding.

Add routing support for following modules of AHUB:
* SFC (Sampling Frequency Converter)
* MVC (Master Volume Control)
* AMX (Audio Multiplexer)
* ADX (Audio Demultiplexer)
* Mixer
These modules can be plugged into audio path as per the need using
routing controls similar to the already existing routes to I/O modules
such as I2S, DMIC and DSPK.

Quite a quiet release this time, mostly a combination of cleanups
and a good set of new drivers.
- Lots of cleanups and improvements to the Intel drivers,
including some new systems support.
- New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek
Mt8195, Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P,
Renesas RZ/G2L,, Rockchip RK3568 S/PDIF.

As the standard buffer allocation helper supports WC pages now, we can
convert imx-pcm-rpmsg driver to use that. This allows us to remove
lots of superfluous code.

DMA memory is currently allocated for the soundcard device, which is a
virtual device added for the sole purpose of "stitching" together the
audio device. It is not a real device and therefore doesn't have a DMA
mask or a description of the path to and from memory of accesses.
Memory accesses really originate from the ADMA controller that provides
the DMA channels used by the PCM component. However, since the DMA
memory is allocated up-front and the DMA channels aren't known at that
point, there is no way of knowing the DMA channel provider at allocation
time.
The next best physical device in the memory path is the ADMAIF. Use it
as the device to allocate DMA memory to. iommus and interconnects device
tree properties can thus be added to the ADMAIF device tree node to
describe the memory access path for audio.
