9 description: |
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
