mfd: Remove dm355evm_msp driver

2022-12-07T13:28:08Z

The DaVinci DM355EVM platform is gone after the removal of all unused board files, so the MTD device along with its sub-devices can be removed as well.

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.

rtc: constify rtc_class_ops structures

2017-01-11T16:23:06Z

Declare rtc_class_ops structures as const as they are only passed as an argument to the function devm_rtc_device_register. This argument is of type const struct rtc_class_ops *, so rtc_class_ops structures having this property can be declared const.
