description:
Some ULPI USB PHYs do not support an internal VBUS supply and driving
the CPEN pin requires the configuration of the UPLI_USE__EXTVBUS
bit in ULPI_BUSCONTROL.

Annotation
- Immediate include surface: `dt-bindings/clock/microchip,mpfs-clock.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- 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.
