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

When enabled, the watchdog peripheral can be used to reset the device if the
WDT is not cleared periodically in software.

Required properties:
- compatible: must be "microchip,pic32mzda-wdt".
- reg: physical base address of the controller and length of memory mapped
  region.
- clocks: phandle of source clk. Should be <&rootclk LPRCCLK>.

Example:

	watchdog@1f800800 {
		compatible = "microchip,pic32mzda-wdt";
		reg = <0x1f800800 0x200>;
		clocks = <&rootclk LPRCCLK>;
	};

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.
