+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.
