First cell is reset request register offset.
Second cell is bit offset in reset request register.
Third cell is bit offset in reset status register.
For LGM SoC, reset cell count is 2 as bit offset in
reset request and reset status registers is same. Whereas
3 for legacy SoCs as bit offset differs.

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.
