I don't feel comfortable to add an acked-by or reviewed-by here
because I don't do much with dt-bindings myself, but this looks
good to me.

From a device tree binding POV, could there be a

nvmem-layout@0 {
  reg = <0>;
  compatible = "layout1";
};

nvmem-layout@1000 {
  reg = <1000>;
  compatible = "layout2";
};

for partitioned eeproms for example?
