2019-04-04rtc: omap: switch to rtc_time64_to_tm/rtc_tm_to_time64Alexandre Belloni
Call the 64bit versions of rtc_time_to_tm now that the range is enforced by the core. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2019-04-04rtc: ps3: set rangeAlexandre Belloni
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>

This allows further improvement of the driver. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2019-04-04rtc: ps3: switch to rtc_time64_to_tm/rtc_tm_to_time64Alexandre Belloni
Call the 64bit versions of rtc_tm time conversion as the PS3 handles 64bit values. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2019-04-04rtc: sh: set rangeAlexandre Belloni
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>
2019-04-04rtc: sh: fix possible race conditionAlexandre Belloni
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.

2019-04-04rtc: sh: stop resetting time to epochAlexandre Belloni
There is no point in resetting the time to epoch as this means that userspace will never get the valuable information that time is actually invalid.
