rtc: da9063: Make IRQ as optional

rtc: da9063: Mark the alarm IRQ as a wake IRQ

2023-08-16T23:09:50+00:00

This keeps the IRQ enabled during system suspend, if the RTC's wakeup source is enabled. Since the IRQ is not required to wake from shutdown, continue to add the wakeup source even if registering the wakeirq fails. See commit 029d3a6f2f3c ("rtc: da9063: add as wakeup source").

rtc: da9063: add as wakeup source

2021-12-02T22:23:38+00:00

As da9063 RTC is not a real I2C client, but relies on da9063 MFD driver, we need to explicitly mark da9063 RTC as a wakeup source to be able to access class/rtc/rtcN/wakealarm sysfs entry to set alarms, so we can wakeup from SHUTDOWN/RTC/DELIVERY mode. As da9063 driver refuses to load without irq, we simply add it as a wakeup source before registering rtc device.

Stop using uie_unsupported and clear RTC_FEATURE_UPDATE_INTERRUPT instead. Also, let the core know that the alarm will truncate seconds as it only has a minute resolution.

rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12+00:00

rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

Pull RTC updates from Alexandre Belloni: "A huge series from me this cycle. I went through many drivers to set the date and time range supported by the RTC which helps solving HW limitation when the time comes (as early as next year for some). This time, I focused on drivers using .set_mms and .set_mmss64, allowing me to remove those callbacks. About a third of the patches got reviews, I actually own the RTCs and I tested another third and the remaining one are unlikely to cause any issues. Other than that, a single new driver and the usual fixes here and there.
