9description: |
10  Any partition containing the compatible "nvmem-cells" will register as a
11  nvmem provider.
12  Each direct subnodes represents a nvmem cell following the nvmem binding.
13  Nvmem binding to declare nvmem-cells can be found in:
14  Documentation/devicetree/bindings/nvmem/nvmem.yaml
