Annotation
- Immediate include surface: `soc/fsl/qe/immap_qe.h`, `soc/fsl/qe/qe.h`.
- Detected declarations: `enum ucc_speed_type`, `function ucc_set_qe_mux_grant`, `function ucc_set_qe_mux_tsa`, `function ucc_set_qe_mux_bkpt`.
- Atlas domain: Repository Root And Misc / include.
- 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.
