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: sun4v: switch to SPDX identifier

2019-04-04T08:07:10+00:00

Use SPDX-License-Identifier to be clearer on the license. Choose the v2 only as this is the default Linux license. Acked-by: David S. Miller Signed-off-by: Alexandre Belloni

rtc: sun4v: set range

2019-04-04T08:07:10+00:00

The Sun4v Hypervisor Core API Specification states: Time is described by a single unsigned 64-bit word equivalent to a time_t for the POSIX time(2) system call. The word contains the time since the Epoch (00:00:00 UTC, January 1, 1970), measured in seconds. Acked-by: David S. Miller Signed-off-by: Alexandre Belloni

rtc: sun4v: switch to rtc_time64_to_tm/rtc_tm_to_time64

2019-04-04T08:07:10+00:00

Call the 64bit versions of rtc_tm time conversion as the hypervisor handles 64bit values. Acked-by: David S. Miller Signed-off-by: Alexandre Belloni

rtc: sparc: make sun4v explicitly non-modular

2016-11-04T22:31:33+00:00

The Kconfig currently controlling compilation of this code is: drivers/rtc/Kconfig:config RTC_DRV_SUN4V drivers/rtc/Kconfig: bool "SUN4V Hypervisor RTC" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. Cc: Alessandro Zummo Cc: Alexandre Belloni Cc: "David S.
