title: NVMEM layout for fixed NVMEM cells
description:
Many NVMEM devices have hardcoded cells layout (offset and size of defined
NVMEM content doesn't change).
This binding allows defining such NVMEM layout with its cells. It can be used
on top of any NVMEM device.

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.
