+Subject: [PATCH] nvmem: core: support passing DT node in cell info
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Some hardware may have NVMEM cells described in Device Tree using
+individual nodes. Let drivers pass such nodes to the NVMEM subsystem so
+they can be later used by NVMEM consumers.
