2019-04-04rtc: sun4v: switch to SPDX identifierAlexandre Belloni1-1/+1
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 <davem@davemloft.net> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2019-04-04rtc: sun4v: set rangeAlexandre Belloni1-3/+5
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 <davem@davemloft.net> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2019-04-04rtc: sun4v: switch to rtc_time64_to_tm/rtc_tm_to_time64Alexandre Belloni1-9/+2
Call the 64bit versions of rtc_tm time conversion as the hypervisor handles 64bit values. Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2016-11-05rtc: sparc: make sun4v explicitly non-modularPaul Gortmaker1-6/+4
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.

2014-10-20rtc: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2013-07-04drivers/rtc/rtc-sun4v.c: remove empty functionSachin Kamat1-6/+0
After the switch to devm_* functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it.
