Partitions that contains the nvmem-partitions compatible will register their direct subonodes as nvmem cells and the node will be treated as a nvmem provider. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

I applied this patch on top of the:
[PATCH] mtd: parsers: ofpart: limit parsing of deprecated DT syntax
I succesfully used NVMEM cell defined in bootloader mtd partition for
reading device MAC address.
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
compatible = "nvmem-partitions";
label = "bootloader";
reg = <0x0 0x100000>;
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 0x0 0x100000>;
base_mac_addr: mac@106a0 {
reg = <0x106a0 0x6>;
};
};
}
