Until now, the of_node of the parent device is used. Some devices
provide more than just the nvmem provider. To avoid name space clashes,
add a way to allow specifying the nvmem cells in subnodes. Consider the
following example:
flash@0 {
compatible = "jedec,spi-nor";
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
reg = <0x000000 0x010000>;
};
};
otp {
compatible = "user-otp";
#address-cells = <1>;
#size-cells = <1>;
serial-number@0 {
reg = <0x0 0x8>;
};
};
};
There the nvmem provider might be the MTD partition or the OTP region of
the flash.
Add a new config->of_node parameter, which if set, will be used instead
of the parent's of_node.
