First we remove unused APIs and the global cell list. We then switch to using kref instead of manual user counting. Next we simplify the provider unregistration by removing the return value from nvmem_unregister(). Next three patches improve the framework by adding a notifier chain for future use and fixing the issue with nvmem device names. Finally we add support for cell definitions, cell lookups and make DT systems resolve the nvmem cells during provider's registration. Last patches just use the SPDX license identifiers and make the naming convention for some arguments more consistent. Tested both DT and non-DT use cases.
