4 Subject: [PATCH] nvmem: u-boot-env: find Device Tree nodes for NVMEM cells
5 MIME-Version: 1.0
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit

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.
