It is not necessary to forward declare pcf85363_driver as it is not used
before being declared.

regmap is abstracting the i2c functionalities the best it can, there is no
need to check.

Add support for NXP pcf85263 real-time clock. pcf85263 rtc is compatible
with pcf85363,except that pcf85363 has additional 64 bytes of RAM.
1 byte of nvmem is supported and exposed in sysfs (# is the instance
number,starting with 0): /sys/bus/nvmem/devices/pcf85x63-#/nvmem

rtc: pcf85363: set time accurately2018-03-17T13:20:49+00:00Alexandre Bellonialexandre.belloni@bootlin.com2018-02-24T00:08:53+00:00urn:sha1:188306ac9536ec47674ffa9dd330f69927679aeb
As per 8.2.6 Setting and reading the time in RTC mode, first stop the clok,
then reset it before setting the date and time registers. Finally, start
the clock.
This uses register address wrap around from 0x2f to 0x00 for efficiency.
This allows to set the clock with a millisecond accuracy (drift is not
corrected in this example):
