Annotated Snippet

RT274 audio CODEC

This device supports I2C only.

Required properties:

- compatible : "realtek,rt274".

- reg : The I2C address of the device.

Optional properties:

- interrupts : The CODEC's interrupt output.


Pins on the device (for linking into audio routes) for RT274:

  * DMIC1 Pin
  * DMIC2 Pin
  * MIC
  * LINE1
  * LINE2
  * HPO Pin
  * SPDIF
  * LINE3

Example:

rt274: codec@1c {
	compatible = "realtek,rt274";
	reg = <0x1c>;
	interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
};

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.
