The PS3 has a 64bit second counter from 2000. While this exceeds the 64bit UNIX timestamp, there is not doubt that non of them will still be working by then. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

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. Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc struct before requesting the IRQ.
