2025-06-02rtc: test: Test date conversion for dates starting in 1900Uwe Kleine-König
While the RTC framework intends to only handle dates after 1970 for consumers, time conversion must also work for earlier dates to cover e.g. storing dates beyond an RTC's range_max. This is most relevant for the rtc-mt6397 driver that has range_min = RTC_TIMESTAMP_BEGIN_1900; range_max = mktime64(2027, 12, 31, 23, 59, 59); and so needs working support for timestamps in 1900 starting in less than three years. So shift the tested interval of timestamps to also cover years 1900 to 1970.

2025-06-02rtc: test: Also test time and wday outcome of rtc_time64_to_tm()Uwe Kleine-König
To cover calculation of the time and wday in the rtc kunit test also check tm_hour, tm_min, tm_sec and tm_wday of the rtc_time calculated by rtc_time64_to_tm(). There are no surprises, the two tests making use of rtc_time64_to_tm_test_date_range() continue to succeed.

2025-06-02rtc: test: Emit the seconds-since-1970 value instead of days-since-1970Uwe Kleine-König
This is easier to handle because you can just consult date(1) to convert between a seconds-since-1970 value and a date string: $ date --utc -d @3661 Thu Jan 1 01:01:01 AM UTC 1970 $ date -d "Jan 1 12:00:00 AM UTC 1900" +%s -2208988800 The intended side effect is that this prepares the test for dates before 1970. The division of a negative value by 86400 doesn't result in the desired days-since-1970 value as e.g. secs=-82739 should map to days=-1.

2025-06-02rtc: Fix offset calculation for .start_secs < 0Alexandre Mergnat
The comparison rtc->start_secs > rtc->range_max has a signed left-hand side and an unsigned right-hand side. So the comparison might become true for negative start_secs which is interpreted as a (possibly very large) positive value. As a negative value can never be bigger than an unsigned value the correct representation of the (mathematical) comparison rtc->start_secs > rtc->range_max in C is: rtc->start_secs >= 0 && rtc->start_secs > rtc->range_max Use that to fix the offset calculation currently used in the rtc-mt6397 driver.

2025-06-02rtc: Make rtc_time64_to_tm() support dates before 1970Alexandre Mergnat
Conversion of dates before 1970 is still relevant today because these dates are reused on some hardwares to store dates bigger than the maximal date that is representable in the device's native format. This prominently and very soon affects the hardware covered by the rtc-mt6397 driver that can only natively store dates in the interval 1900-01-01 up to 2027-12-31. So to store the date 2028-01-01 00:00:00 to such a device, rtc_time64_to_tm() must do the right thing for time=-2208988800.

2025-06-02rtc: pcf8563: fix wrong alarm registerTroy Mitchell
When the regmap framework was introduced to this driver, the PCF8563_REG_AMN register within the set_alarm function was incorrectly changed to PCF8563_REG_SC. The PCF8563_REG_SC register is the seconds register. This caused alarm values to be written to the seconds register when an alarm was set. Which means the alarm would not trigger as expected and the seconds register would be overwritten with an incorrect value.
