| Subject: [PATCH] nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |

| 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. |
