* rtc: max8997: Fix the returned value in case of error in ↵Christophe JAILLET2018-11-221-1/+1
| | | | | | | | | | | 'max8997_rtc_read_alarm()' In case of error, we return 0. This is spurious and not consistent with the other functions of the driver. Propagate the error code instead.

* rtc: stop validating rtc_time in .read_timeAlexandre Belloni2018-03-021-1/+1
| | | | | | | The RTC core is always calling rtc_valid_tm after the read_time callback. It is not necessary to call it just before returning from the callback. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

| | | | | | | | | These platform drivers have a platform device ID table but the module alias information is not created so module autoloading will not work.

* rtc: max8997: add driver for max8997 rtcJonghwa Lee2013-02-211-0/+553
Add an rtc driver for Maxim 8997 multifunction chip. Max8997 has rtc module in it. and it can be used for timekeeping clock and system alarm. It provide various operational mode those are BCD/binary, 24/12hour, am/pm. Driver sets binary/24/ for default. Maxim 8997 also supports SMPL(Sudden Momentary Power Loss), WTSR (Watchdog Timeout and Software Reset).
