Annotation
- Immediate include surface: `dt-bindings/clock/imx93-clock.h`, `dt-bindings/dma/fsl-edma.h`, `dt-bindings/gpio/gpio.h`, `dt-bindings/input/input.h`, `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/power/fsl,imx93-power.h`, `dt-bindings/thermal/thermal.h`, `imx93-pinfunc.h`.

- 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.
