If it's missing, it is assumed that the phandle has no arguments. Up until now, a nvmem node didn't have any arguments, so all the device trees haven't any '#*-cells' property. But there is a need for an additional argument for the phandle, for which we need a '#*-cells' property. Therefore, we need to support nvmem nodes with and without this property.

For example, a base ethernet address stored in the NVMEM can be expanded into multiple discreet ones by adding an offset. For this use case, introduce an index parameter which is then used to distiguish between values. This parameter will then be passed to the post process hook which can then use it to create different values during reading. At the moment, there is only support for the device tree path. You can add the index to the phandle, e.g. &net { nvmem-cells = <&base_mac_address 2>; nvmem-cell-names = "mac-address"; }; &nvmem_provider { base_mac_address: base-mac-address@0 { #nvmem-cell-cells = <1>;

For example, a MAC address might be stored in ASCII representation or we might need to swap bytes. We might also want to expand one value to mutliple ones, for example, the nvmem cell might just store a base MAC address to which we need to add an offset to get an address for different network interfaces. Add initial support to add such transformations based on the device tree compatible string of the NVMEM device. It will reuse the nvmem post process hook. Both are mutually exclusive.
