Annotation
- Immediate include surface: `dt-bindings/gpio/gpio.h`, `dt-bindings/input/input.h`, `dt-bindings/leds/common.h`, `dt-bindings/pinctrl/rockchip.h`, `dt-bindings/pwm/pwm.h`, `dt-bindings/soc/rockchip,vop2.h`, `dt-bindings/usb/pd.h`, `rk3588-firefly-core-3588j.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.
