Annotation
- Immediate include surface: `dt-bindings/bus/ti-sysc.h`, `dt-bindings/clock/dra7.h`, `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/pinctrl/dra.h`, `omap4-cpu-thermal.dtsi`, `omap5-gpu-thermal.dtsi`, `omap5-core-thermal.dtsi`, `dra7-dspeve-thermal.dtsi`.

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.
