This patchset adds support for the EPSON RX8035 real time
clock to the rx8025 driver. The two devices are very similar
and with only minor differences for basic real time clock functions.

Some issues have been identified with the handling of date
setting and clock reset with the U-Boot driver which are resolved
with these patches.

It appears only one board (socrates) in the U-Boot tree uses this driver
at present, the other users either not in tree or removed under
previous cleanups, so take this opportunity to remove non_DM-RTC
support as well, and vestiges of previous board specific hacks.

The Traverse Technologies Ten64 board will be introduced in the 
near future and it will use this driver.

Mathew McBride (4):
  rtc: rx8025: drop non-DM support
  rtc: rx8025: add support for EPSON RX8035.
  rtc: rx8025: set date in a single i2c transaction
  rtc: rx8025: revise single register write to use offset
