[PATCH 00/45] RTC: nvmem improvements

[Alexandre Belloni]

This series makes some change to the RTC nvmem API to simplify drivers
and clean the way the nvmem_config is used.

The main issue was the different lifecycle of the struct nvmem_config
(only needed at probe time) and rtc_device (needed for the lifetime of
the driver).

Then, it converts the remaining drivers (except ds1685) to the API. A
few other improvements are also made along the way.

Alexandre Belloni (45):
  rtc: documentation: correct nvmem date and version
  rtc: nvmem: pass nvmem_config to rtc_nvmem_register()
