Please take a look at those commits and examples:
bd912c991d2e ("dt-bindings: nvmem: layouts: add fixed-layout")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=bd912c991d2ef079a32558f057b8663bcf1fb6fc
fa7fbe53ecdc ("dt-bindings: nvmem: convert base example to use NVMEM
fixed cells layout")
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fa7fbe53ecdc4e7d549a9f73a40e257b0046b4b9
Basically you need a "nvmem-layout" node with:
compatible = "fixed-layout";
So in your case that would be:
&{flash/partitions} {
compatible = "fixed-partitions";
partition@0 {
reg = <0 0x100>;
nvmem-layout {
compatible = "fixed-layout";
#address-cells = <1>;
#size-cells = <1>;
calib@1 {
reg = <1 1>;
};
};
}
};
