From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> This series contains nvmem framework changes prerequisite for further development of my previous series[1] that aims at removal of the platform data struct from at24 EEPROM driver. 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 patch just uses the SPDX license identifiers. Tested both DT and non-DT use cases.
