rtc: cleanup obsolete comment about struct rtc_class_ops

2020-07-16T11:35:25+00:00

Commit ea369ea6d828 ("rtc: remove .open() and .release()") removes
open/release callback from struct rtc_class_ops.

Also commit 80d4bb515b78 ("RTC: Cleanup rtc_class_ops->irq_set_state")
and commit 696160fec162 ("RTC: Cleanup rtc_class_ops->irq_set_freq()")
removes irq callbacks.

So, just remove related comments so that readers will not be confused.

making 2079 the last supported year.

rtc: add a timestamp for year 0

2019-10-07T13:49:22+00:00

A few RTCs handle dates from year 0 to year 9999. Add a timestamp even if
years before 1970 will probably never be used.

rtc: drop set_mms and set_mmss64

2019-05-08T20:14:36+00:00

There are no users of set_mms and set_mmss64 as they have all been
converted to set_time and are handling the tm to time conversion on their
own.

rtc: sh: set range

2019-04-04T08:07:09+00:00

The SH RTC is a BCD RTC with some version having 4 digits for the year.

The range for the RTCs with only 2 digits for the year was unfortunately
shifted to handle 1999 to 2098.
