description: |
Broadcom "Low Speed" SPI controller found in many older MIPS based Broadband
SoCs.
This controller has a limitation that can not keep the chip select line active
between the SPI transfers within the same SPI message. This can terminate the
transaction to some SPI devices prematurely. The issue can be worked around by
the controller's prepend mode.

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.
