Subject: [PATCH 00/10] Audio graph card updates and usage with Tegra210 audio
This series proposes following enhancements to audio-graph card driver.
* Support multiple instances of a component.
* Support Codec port with multiple endpoints.
* Support open platforms with empty Codec endpoint.
* Identify no-pcm DPCM DAI links which can be used in BE<->BE connections.
* Add new compatible to support DPCM based DAI chaining.
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)
