   4 Subject: [PATCH] nvmem: u-boot-env: find Device Tree nodes for NVMEM cells
   5 MIME-Version: 1.0

   9 DT binding allows specifying NVMEM cells as NVMEM device (provider)
  10 subnodes. Looks for such subnodes when building NVMEM cells.
  11
  12 This allows NVMEM consumers to use U-Boot environment variables.
