rtc: Include when appropriate

2022-11-15T20:01:51+00:00

The kstrto() functions have been moved from kernel.h to
kstrtox.h.

So, include the latter directly in the appropriate files.

rtc: rx8025: Convert to .probe_new()

2022-11-15T20:01:33+00:00

.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in .probe().

rtc: rx8025: fix 12/24 hour mode detection on RX-8035

2022-07-26T14:49:45+00:00

The 12/24hr flag in the RX-8035 can be found in the hour register,
instead of the CTRL1 on the RX-8025. This was overlooked when
support for the RX-8035 was added, and was causing read errors when
the hour register 'overflowed'.

To deal with the relevant register not always being visible in
the relevant functions, determine the 12/24 mode at startup and
store it in the driver state.

rtc: rx8025: use .set_offset/.read_offset

2021-11-09T23:45:57+00:00

The driver has its own sysfs file to adjust the clock. Fortunately, it is
already in pbb, however, the sign it expects is the opposite of what the
RTC core does (which actually aligns with the RTC).

Set the RTC range, it is a classic BCD RTC, with 00 being a leap
