When compiled with CONFIG_HAVE_CLK, the kernel need to get provider for the
clock API. This is usually selected by the platform and the sound drivers
should not really care about this. However COMPILE_TEST is special and the
platform required may not have been selected, leading to this type of
error:
> aiu-encoder-spdif.c:(.text+0x3a0): undefined reference to `clk_set_parent'
Since we need a sane provider of the API with COMPILE_TEST, depends on
COMMON_CLK.

The SOF (Sound Open Firmware) tree contains a lot of references in
topology files to 'codec_slave'/'codec_master' terms, which in turn
come from alsa-lib and ALSA/ASoC topology support at the kernel
level. These terms are no longer compatible with the guidelines
adopted by the kernel community [1], standard organizations, and need
to change in backwards-compatible ways.
The main/secondary terms typically suggested in guidelines don't mean
anything for clocks, this patchset suggests instead the use of
'provider' and 'consumer' terms, with the 'codec' prefix kept to make
it clear that the codec is the reference. The CM/CS suffixes are also
replaced by CP/CC.
It can be argued that the change of suffix is invasive, but finding a
replacement that keeps the M and S shortcuts has proven difficult in
quite a few contexts.
The previous definitions are kept for backwards-compatibility so this
change should not have any functional impact. It is suggested that new
contributions only use the new terms but there is no requirement to
transition immediately to the new definitions for existing code. Intel
will however update all its past contributions related to bit
clock/frame sync configurations immediately.
This patchset contains the kernel changes only, the alsa-lib changes
were shared separately.
Feedback welcome

SND_INTEL_DSP_CONFIG is selected by the HDaudio, Skylake and SOF
drivers. When the HDaudio link is not selected as a option, this
Kconfig option is not touched and will default to whatever other
drivers selected. In the case e.g. where HDaudio is compiled as
built-in, the linker will complain:
ld: sound/soc/sof/sof-pci-dev.o: in function `sof_pci_probe':
sof-pci-dev.c:(.text+0x5c): undefined reference to
`snd_intel_dsp_driver_probe'
Adding the select for all HDaudio platforms, regardless of whether
they rely on the HDaudio link or not, solves the problem.

We can choose to drop away any length of data from the beginning according
to project needs. Some projects don't want to throw away any data, because
they want to use recorded data to do echo cancellation, so they have to
make sure that they are aligned with the reference data as much as
possible. Or there are other algorithms in the upper layer to eliminate
this noise. Or some projects want to eliminate this noise form the kernel
layer. However, the minimum recommended value is 50ms to skip pop noise.

This series is a prepraration for using generic graph driver for Tegra210
audio. Tegra audio graph series will be sent in a separate series because
it has some dependency over other series for documentation work. This
series can focus on the generic ASoC driver updates. Below are the summary
of changes done.
* Support multiple instances of a component. For example there can be
multiple I2S devices which can use the same component driver.
* Support open platforms with empty Codec endpoint. Customers can plug
their own HW and can populate codec endpoint.
* In a component model there can be many components which can be
connected together. In such cases Identify no-pcm DPCM DAI links which
can be used in BE<->BE connections.
* Expose structures or helpers to be re-used by other similar graph
drivers.
The series is based on following references where DPCM usgae for Tegra
Audio and simple-card driver proposal were discussed.
* https://lkml.org/lkml/2020/4/30/519 (DPCM for Tegra)
* https://lkml.org/lkml/2020/6/27/4 (simple-card driver)
Changelog
=========
v4 -> v5
--------
* No changes in the core/audio-graph driver patches which are
part of the current series.
* Dropped Tegra audio patches and doc patches. This will be
sent separately once the doc depdendencies are resolved.
v3 -> v4
--------
* Added new patches to convert graph.txt and audio-graph-card.txt
to corresponding json-schema files. Later these references
are used in Tegra audio graph schema.
* AHUB component binding docs are updated to reflect the usage
of ports/port/endpoint
* More common stuff is moved into graph_parse_of() and this is
used by both generic and Tegra audio graph.
* DT binding for Tegra audio graph is updated to included "ports { }"
* As per the suggestion 'void *data' member is dropped from
'asoc_simple_priv' and instead container method is used to
maintain required custom data internal to Tegra audio graph.
v2 -> v3
--------
* Dropped new compatible addition in generic graph driver
after reviewing it with Morimoto-san. Instead added Tegra
audio graph driver and new compatibles are added in the same.
* Added new patches to expose new members for customization
in audio graph driver.
* Added new patch for Tegra audio graph driver and related
documentation.
* Minor change in below commit where mutex version of helper is used
"ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM"
* DT binding is updated to use the newly exposed compatibles
* No changes in other patches
v1 -> v2
--------
* Re-organized ports/endpoints description for ADMAIF and XBAR.
Updated DT patches accordingly.
* After above change, multiple Codec endpoint support is not
required and hence dropped for now. This will be considered
separately if at all required in future.
* Re-ordered patches in the series.

2.7.4
There are two issues in this function.
1) We can't drop the refrences on "cpu", "codec" and "platform" before
we take the reference. This doesn't cause a problem on the first
iteration because those pointers start as NULL so the of_node_put()
is a no-op. But on the subsequent iterations, it will lead to a use
after free.
2) If the devm_kzalloc() allocation failed then the code returned
directly instead of cleaning up.

This commit exposes following functions which can be used by a sound
card driver based on generic audio graph driver. Idea is vendors can
have a thin driver and re-use common stuff from audio graph driver.
- graph_card_probe()
- graph_parse_of()
In doing so a new header file is added for above. The graph_probe()
function is simplified by moving more common stuff to graph_parse_of().

Add new members in struct 'asoc_simple_priv'. Idea is to leverage
simple or graph card driver as much as possible and vendor can
maintain a thin driver to control the behavior by populating these
newly exposed members.
Following are the members added in 'asoc_simple_priv':
- 'ops' struct: In some cases SoC vendor drivers may want to
implement 'snd_soc_ops' callbacks differently. In such cases
custom callbacks would be used.
- 'force_dpcm' flag: Right now simple or graph card drivers
detect DAI links as DPCM links if:
* The dpcm_selectable is set AND
* Codec is connected to multiple CPU endpoints or aconvert
property is used for rate/channels.
So there is no way to directly specify usage of DPCM alone. So a
flag is exposed to mark all links as DPCM. Vendor driver can
set this if required.
- 'dpcm_selectable': Currently simple or audio graph drivers
provide a way to enable this for specific compatibles. However
vendor driver may want to define some additional info. Thus
expose this variable where vendor drivers can set this if
required.
Audio graph driver is updated to consider above flags or callbacks.
Subsequent patches in the series illustrate usage for above.

For open platforms, which can support pluggable audio cards, Codec
endpoint is not fixed always. It actually depends on the compatible
HW module that is going to be connected. From SoC side the given I/O
interface is always available. Hence such links have fixed CPU endpoint
but no Codec endpoint. This patch helps to support such links where
user can populate Codec endpoint only and its fields in Platform DT
depending on the plugged HW.

PCM devices are created for FE dai links with 'no-pcm' flag as '0'.
Such DAI links have CPU component which implement either pcm_construct()
or pcm_new() at component or dai level respectively. Based on this,
current patch exposes a helper function to identify such components
and populate 'no_pcm' flag for DPCM DAI link.
This helps to have BE<->BE component links where PCM devices need
not be created for CPU component involved in such links.

For multiple instances of components, using DAI name alone for DAI links
is causing conflicts. Components can define multiple DAIs and hence using
just a device name won't help either. Thus DT device node reference and
DAI names are used to uniquely represent DAI link names.

dpcm_end_walk_at_be() stops the graph walk when first BE is found for
the given FE component. In a component model we may want to connect
multiple DAIs from different components. A new flag is introduced in
'snd_soc_card', which when set allows DAI/component chaining. Later
