rtc: Add Starfire platform RTC driver. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-28 23:02:36 -07:00
rtc: sparc: make starfire explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/rtc/Kconfig:config RTC_DRV_STARFIRE drivers/rtc/Kconfig: bool "Starfire 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.

rtc: rework rtc_register_device() resource management 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.
