This patch set aims to add support for NXP pcf85263 real-time clock. 
pcf85263 rtc is compatible with pcf85363 rtc except that pcf85363 has
64 bytes additional RAM. 

1 byte of nvmem is supported in pcf85263 and is exposed through sysfs.

The details of pcf85363 and pcf85263 can be found in the below
data sheets.
