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:
  Documentation/devicetree/bindings/nvmem/nvmem.yaml
