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

Detected Declarations

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

Annotated Snippet

IBM OPAL real-time clock
------------------------

Required properties:
- compatible: Should be "ibm,opal-rtc"

Optional properties:
- wakeup-source: Decides if the wakeup is supported or not
		 (Legacy property supported: "has-tpo")

Example:
	rtc {
		compatible = "ibm,opal-rtc";
		wakeup-source;
		phandle = <0x10000029>;
		linux,phandle = <0x10000029>;
	};

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.
