Annotated Snippet

AK4118 S/PDIF transceiver

This device supports I2C mode.

Required properties:

- compatible : "asahi-kasei,ak4118"
- reg : The I2C address of the device for I2C
- reset-gpios: A GPIO specifier for the reset pin
- irq-gpios: A GPIO specifier for the IRQ pin

Example:

&i2c {
	ak4118: ak4118@13 {
		#sound-dai-cells = <0>;
		compatible = "asahi-kasei,ak4118";
		reg = <0x13>;
		reset-gpios = <&gpio 0 GPIO_ACTIVE_LOW>
		irq-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
	};
};

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.
