Support for old NVMEM fixed cells was deprecated in favour of "fixed-layout". It's still part of the nvmem.yaml though and may be unknowingly used by new bindings added without much of analyze. To make it more difficult to accidentally support old syntax move its binding to separated file with "deprecated" in its name.

title: Nvmem cells
|
|
|
|
description: |
|
|
Any partition containing the compatible "nvmem-cells" will register as a
|
|
nvmem provider.
|
|
Each direct subnodes represents a nvmem cell following the nvmem binding.
|
|
Nvmem binding to declare nvmem-cells can be found in:
