Overall am still not able to clear visualize on how MTD bindings with 
nvmem cells would look in both partition and un-partition usecases?
An example DT would be nice here!!  

Something along those lines:

We must also have a compatible string on the nvmem-cells node to make
sure we don't clash with the old style MTD partitions, or some other
device specific binding.

	mtdnode {
		nvmem-cells {

                        compatible = "nvmem-cells";

			#address-cells = <1>;
			#size-cells = <1>;

			cell@0 {
				reg = <0x0 0x14>;
			};
		};

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				reg = <0x0 0x20000>;

				nvmem-cells {

                                        compatible = "nvmem-cells";

					#address-cells = <1>;
					#size-cells = <1>;

					cell@0 {
						reg = <0x0 0x10>;
					};
				};
			};
		};
	};
