rtc: tps65910: Remove redundant dev_warn() and do not check for 0 return after calling platform_get_irq()

2023-08-16T23:17:34+00:00

It is not possible for platform_get_irq() to return 0. Use the return value from platform_get_irq(). And there is no need to call the dev_warn() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.

rtc: tps65910: Correct driver module alias

2021-08-17T21:36:22+00:00

The TPS65910 RTC driver module doesn't auto-load because of the wrong module alias that doesn't match the device name, fix it.

rtc: tps65910: Support wakeup-source property

2021-01-25T22:57:24+00:00

TPS65910 is a PMIC MFD device and RTC is one of its functions. The wakeup-source DT property is specified for the parent MFD device and we need to use this property for the RTC in order to allow to use RTC alarm for waking up system from suspend by default, instead of requiring user to enable wakeup manually via sysfs.

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.

2019-11-17T21:24:33+00:00

If tps65910 INT1 pin (IRQ output) is not wired to any IRQ controller, then it can't be used as system wakeup/alarm source, but it is still possible to read/write time from/to RTC.
