Subject: [PATCH 0/3] Generic SPMI NVMEM cell driver

Hi.

This patch series adds a driver for exposing a set of SPMI registers
as NVMEM cells. This is used on Apple ARM platforms to store the RTC
offset and to communicate platform power state between the OS and
boot firmware.

The NVMEM cell consumer drivers will be sent in a further series.
