From: Rafał Miłecki <rafal@milecki.pl> 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. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> --- drivers/nvmem/brcm_nvram.c | 2 ++ 1 file changed, 2 insertions(+)
