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.
