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.

Changelog =========
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.
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
