Hi Mark, Morimoto-san,
Summary of changes:
* 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 togethe. In such cases Identify no-pcm DPCM DAI links which
can be used in BE<->BE connections.
* Add Tegra audio graph driver which is based on generic audio graph
driver and specific customizations are done in Tegra driver.
* This pushes DT support for Tegra210 based platforms which uses
audio-graph card and above enhancements.
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
=========
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.

Would you suggest to keep above in a separate series and thus not
blocked by below doc updates? If so do I need to resend above in a next
revision or if these are good to be picked up?
Documentation: of: Convert graph bindings to json-schema
ASoC: dt-bindings: audio-graph: Convert bindings to json-schema
ASoC: dt-bindings: tegra: Add graph bindings
ASoC: dt-bindings: tegra: Add json-schema for Tegra audio graph card
Documentation patches in the series have some dependency over
Morimoto-san's audio-graph series
https://patchwork.kernel.org/project/alsa-devel/list/?series=372759. I
will update doc related patches once dependency is merged.
