I'm not familiar with your system, so, one question.
Does this ADMAIF has total 10 interface which is used in the same time ?
or select one of 10 connections when use ?
One ore more ADMAIF interfaces can be used simultaneously. In fact all
of them can be used at the same time.
Ah, sorry my questoin was not correct.
I want to clarify was that below.
In my understanding,
if your system has 10 interfaces,
you need to create 10 ports, not 10 endpoints.
If your system has 1 interface, but is connected from 10
devices, it has 1 port 10 endpoints.
OK, I see your point. I will work on re-organizing ports/endpoints and
once tested will publish V2 for current series. Thanks for inputs.
Thank you for your help !!
Best regards

[PATCH 09/10] arm64: tegra: Audio graph header for Tegra210
Expose a header which describes DT bindings required to use audio-graph
based sound card. All Tegra210 based platforms can include this header
and add platform specific information. Currently, from SoC point of view,
all links are exposed for ADMAIF, AHUB, I2S and DMIC components.
