[PATCH v4 15/15] arm64: tegra: Audio graph sound card for Jetson Nano and TX1

From: Sameer Pujar
Date: Fri Oct 16 2020 - 10:45:04 EST


Enable support for audio-graph based sound card on Jetson-Nano and
Jetson-TX1. Depending on the platform, required I/O interfaces are
enabled.

* Jetson-Nano: Enable I2S3, I2S4, DMIC1 and DMIC2.
* Jetson-TX1: Enable all I2S and DMIC interfaces.
