Call the 64bit versions of rtc_tm time conversion to allow extending support after 2106 and properly supporting the STv2 range. Acked-by:
-
Alexandre Belloni authored
The PL031 and ST v1 RTC are 32bit seconds counters. STv2 is a BCD RTC apparently going from 0000 to 9999, hopefully handling the leap days properly until then. Reviewed-by:

The datasheet states that 4052 is the maximum value for year. However, the mpc5121 read_time and set_time function abuse the target time register instead of using the broken down time so it is limited to 2106.

The RTC IRQ is requested before the struct rtc_device is allocated, this may lead to a NULL pointer dereference in the IRQ handler. To fix this issue, allocating the rtc_device struct before requesting the RTC IRQ using devm_rtc_allocate_device, and use rtc_register_device to register the RTC device.

Let the core handle offsetting and windowing the RTC range. This rtc has hours, minutes, seconds and 16bit days. As the driver has the RTC epoch set to year 2000, this means that the end of the range is 2^16 days minus one second later. This is Sun Jun 6 23:59:59 UTC 2179. This is better than the currently set year 2099. Link: https://lore.kernel.org/r/20200305215022.32533-3-alexandre.belloni@bootlin.comSigned-off-by:

The code handling invalid alarms meaning the alarm is in the next 24 hours is not necessary since commit f8245c26 ("rtc: remove "RTC_ALM_SET mode" bugs") which actually predates this driver. Since then, .set_alarm is never called with an invalid alarm and this handling is not necessary in the driver.

This RTC is a 32bit counter running at 16Hz. This overflows every eight years and a half. However, the driver uses the SW_VALUE register to store the overflow, extending the counter to 64bit as long as the update happens before the overflow.
