title: MDIO bus multiplexer found in Broadcom iProc based SoCs.

description:
This MDIO bus multiplexer defines buses that could be internal as well as
external to SoCs and could accept MDIO transaction compatible to C-22 or
C-45 Clause. When child bus is selected, one needs to select these two
properties as well to generate desired MDIO transaction on appropriate bus.

Annotation
- 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.
