rtc: m48t59: Use platform_data struct for year offset value

2024-11-18T13:31:57+00:00

Instead of hard-coded values and ifdefs, store the year offset in the platform_data struct.

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.

rtc: add devm_ prefix to rtc_nvmem_register()

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

rtc_nvmem_register() is a managed interface. It doesn't require any release function to be called at driver detach. To avoid confusing driver authors, let's rename it to devm_rtc_nvmem_register() and add it to the list of managed interfaces in Documentation/.
