title: NVIDIA Tegra20 I2S Controller
description: |
The I2S Controller streams synchronous serial audio data between system
memory and an external audio device. The controller supports the I2S Left
Justified Mode, Right Justified Mode, and DSP mode formats.

limiting number of supportable audio rates.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
