Annotation
- Immediate include surface: `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/interrupt-controller/irq.h`, `dt-bindings/leds/common.h`, `dt-bindings/leds/leds-pca9532.h`.
- Atlas domain: Architecture Layer / arch/arm.
- 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.
