Some boards, like OrangePi PC2 (H5), OrangePi Plus 2E (H3) and Tanix TX6 (H6) don't have external 32kHz oscillator. Till H6, it didn't really matter if external oscillator was enabled because HW detected error and fall back to internal one. H6 has same functionality but it's the first SoC which have "auto switch bypass" bit documented and always enabled in driver. This prevents RTC to work correctly if external crystal is not present on board. There are other side effects - all peripherals which depends on this clock also don't work (HDMI CEC for example). Make clocks property optional. If it is present, select external oscillator. If not, stay on internal. Signed-off-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.
