[PATCH v3 00/14] rtc: rx8010: use regmap instead of i2c smbus API

This series gets bigger and bigger but I noticed a problem with this
driver that looks like stable material so I fixed it as the first patch
in the series to make backporting easy.

Other than that, there are new refactoring patches and I removed the
unnecessary error messages.

I want to use this driver on a platform where the i2c controller doesn't
speak SMBUS. This series converts the driver to i2c regmap which can
figure out the correct protocol to use.

The actual conversion happens in patch 13. The rest are bugfixes and
refactoring.

v1 -> v2:
- s/parentheses/brackets/g
- add a patch switching the driver to using the preferred RTC API
- rework the patch removing magic values
- use range_max and range_min instead of manual range checks
- add a patch adding a helper variable in probe() for client->dev
- add a patch using sizeof(*rx8010) instead of sizeof(struct rx8010_data)

v2 -> v3:
- remove unnecessary error messages when registering the RTC device
- add a patch switching to using the preferred probe_new callback in
the I2C driver
- add a patch fixing an issue where the global rtc operations struct
is modified depending on the presence of the interrupt
- add a patch removing a stray newline
