rtc: ds1511: set alarm offset limit

2024-02-29T21:16:52Z

The ds1511 can only support alarms up to a month in the future (which we currently limit to 28 days). Link: https://lore.kernel.org/r/20240227231356.1840523-2-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: set range

2024-02-29T21:16:52Z

The ds1511 leap year calculation fails in 2100. Link: https://lore.kernel.org/r/20240227231356.1840523-1-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: drop inline/noinline hints

2024-02-29T21:15:47Z

There is no reason to not let the compiler optimise those functions as it wants. Link: https://lore.kernel.org/r/20240227230431.1837717-12-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: rename pdata

2024-02-29T21:15:47Z

pdata is not actually about patform_data, rename it to something local to the driver. Link: https://lore.kernel.org/r/20240227230431.1837717-11-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: implement ds1511_rtc_read_alarm properly

2024-02-29T21:15:47Z

ds1511_rtc_read_alarm was useless as it is only called at boot time so the alarm members of pdata have not yet been set. Read the actual registers so there is a chance to get a meaningful value. Then, drop the alarm related members of pdata as they are not used anymore. Link: https://lore.kernel.org/r/20240227230431.1837717-10-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: remove partial alarm support

2024-02-29T21:15:47Z

The RTC core will always provide an alarm with all its members set, it is not necessary to support partial alarms. Link: https://lore.kernel.org/r/20240227230431.1837717-9-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: let the core know when alarm are not supported

2024-02-29T21:15:47Z

Instead of failing function calls, let the core know alarms are not supported so it can fail early and avoid unnecessary calls. Link: https://lore.kernel.org/r/20240227230431.1837717-8-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: remove ds1511_rtc_update_alarm

2024-02-29T21:15:47Z

ds1511_rtc_update_alarm is called twice but one of the call is overkill as it only has to enable or disable the alarm instead of updating all the alarm registers. Merge it in its main call site and introduce a new finction to enable or disable the alarm.

rtc: ds1511: remove incomplete UIE support

2024-02-29T21:15:47Z

There is no way to enable UIE in the driver, drop RTC_UF support. Link: https://lore.kernel.org/r/20240227230431.1837717-6-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: ds1511: fix function definition
