But can you please explain what is the technical/conceptual issue with
this approach ?

Thanks,
I just I'd like to clarify if there is a way it can be acceptable. The
problem is that there is TLV format which might be used on any nvmem
device which contains for example mac address which needs to be exposed
as nvmem cell. If to populate cells via nvmem_config then anyway I need
to parse these cells from the "target" nvmem device.



As a first step this need to be part of the provider logic to parse this before nvmem provider is registered. If there are more users for such parsing, we can think of adding some level of parsing to nvmem core itself.

Hope this answers your query.

Thanks,
