Annotation

• Immediate include surface: `dt-bindings/mfd/stm32f7-rcc.h`, `dt-bindings/clock/stm32fx-clock.h`, `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/clock/stm32mp1-clks.h`, `dt-bindings/reset/stm32mp1-resets.h`.
• 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.
