Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

Required properties:
  - compatible: "atmel,at91sam9263-ac97c"
  - reg: Address and length of the register set for the device
  - interrupts: Should contain AC97 interrupt
  - ac97-gpios: Please refer to soc-ac97link.txt, only ac97-reset is used
Optional properties:
  - pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt

Example:
sound@fffa0000 {
       compatible = "atmel,at91sam9263-ac97c";
       pinctrl-names = "default";
       pinctrl-0 = <&pinctrl_ac97>;
       reg = <0xfffa0000 0x4000>;
       interrupts = <18 IRQ_TYPE_LEVEL_HIGH 5>;

       ac97-gpios = <&pioB 0 0 &pioB 2 0 &pioC 29 GPIO_ACTIVE_LOW>;
};

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.
