+Subject: [PATCH] nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+DT binding for Broadcom's NVRAM supports specifying NVMEM cells as NVMEM
+device (provider) subnodes. Look for such subnodes when collecing NVMEM
+cells. This allows NVMEM consumers to use NVRAM variables.
