rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12Z

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.

The ab3100 has a 48bit counter running at 65536 Hz (despite one of the comment). The max value is then (2^48 - 1)/2^16 == 2^32 - 1. Reviewed-by: Linus Walleij Signed-off-by: Alexandre Belloni

drivers/rtc/ab3100: Update driver to address y2038/y2106 issues

2015-04-03T06:18:25Z

This driver has a number of y2038/y2106 issues. This patch resolves them by: - Replacing rtc_tm_to_time() with rtc_tm_to_time64() - Replacing rtc_time_to_tm() with rtc_time64_to_tm() - Changing ab3100_rtc_set_mmss() to use rtc_class_ops's set_mmss64() After this patch, the driver should not have any remaining y2038/y2106 issues.

rtc: rtc-ab3100: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:48Z

The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Cc: Lars-Peter Clausen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
