- Immediate include surface: `linux/types.h`.
- Detected declarations: `struct clk`, `struct platform_device`, `struct fsl_usb2_platform_data`, `struct spi_device`, `struct fsl_spi_platform_data`, `struct mpc8xx_pcmcia_ops`, `enum fsl_usb2_controller_ver`, `enum fsl_usb2_operating_modes`, `enum fsl_usb2_phy_modes`, `function fsl_deep_sleep`.
- Atlas domain: Core OS / Core Kernel Interface.
- Implementation status: source implementation candidate.
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.
