Subject: [PATCH] nvmem: u-boot-env: find Device Tree nodes for NVMEM cells
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
DT binding allows specifying NVMEM cells as NVMEM device (provider)
subnodes. Looks for such subnodes when building NVMEM cells.
This allows NVMEM consumers to use U-Boot environment variables.
