2018-09-28rtc: test: Switch to SPDX identifierAlexandre Belloni
Replace the license boilerplate by an SPDX identifier Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-09-28rtc: test: make license text and module license match.Alexandre Belloni
The license text is specifying GPL v2 only but the MODULE_LICENSE is set to GPL which means GNU Public License v2 or later. When MODULE_LICENSE and boiler plate does not match, go for boiler plate license. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-07-12rtc: test: make array pdev staticColin Ian King
The array pdev is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: symbol 'pdev' was not declared. Should it be static? Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-06-07rtc: test: remove alarm support from the first deviceAlexandre Belloni
To test for issues with RTCs that don't provide an alarm, remove alarm support from the first test RTC device. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-06-07rtc: test: convert to devm_rtc_allocate_deviceAlexandre Belloni
This allows further improvement of the driver. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-31rtc: test: remove irq sysfs fileAlexandre Belloni
Now that alarms are emulated, remove the irq sysfs file that could be used to send alarms. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-31rtc: test: emulate alarms using timersAlexandre Belloni
Use timers to emulate alarms. Note that multiple alarms may happen if they are set more than 15 days after the current RTC time. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-31rtc: test: store time as an offset to system timeAlexandre Belloni
Store the time as an offset to system time. As the offset is in second, it is currently always synced with system time. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-31rtc: test: allow registering many devicesAlexandre Belloni
Use a loop to register RTC devices Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-31rtc: test: remove useless proc infoAlexandre Belloni
The rtc proc callback is useless for two reasosn: - the test RTC is often not the first RTC so it will never be used - all the info is available in the name file of the RTC sys folder Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-26rtc: test: remove obsolete .set_mmssAlexandre Belloni
There is no point in testing .set_mmss versus .set_mmss64 as there are both taking the exact same argument (truncated for set_mmss though). Also, this allows to constify struct rtc_ops. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2018-05-03rtc: simplify getting .drvdataWolfram Sang
We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth.

2015-04-03drivers/rtc/test: Update driver to address y2038/y2106 issuesXunlei Pang
This driver has a number of y2038/y2106 issues. This patch resolves them by: - Replacing get_seconds() with ktime_get_real_seconds() - Replacing rtc_time_to_tm() with rtc_time64_to_tm() Also add test_rtc_set_mmss64() for testing rtc_class_ops's set_mmss64(), which can be activated by "test_mmss64" module parameter.

2013-01-03Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-17drivers/rtc/rtc-test.c: avoid calling platform_device_put() twiceWei Yongjun
In case of error, test_init() needs to call platform_device_del() instead of platform_device_unregister(). Otherwise, we may call platform_device_put() twice. dpatch engine is used to auto generate this patch.

2011-03-09RTC: Fix the cross interrupt issue on rtc-test.Marcelo Roberto Jimenez
The rtc-test driver is meant to provide a test/debug code for the RTC subsystem. The rtc-test driver simulates specific interrupts by echoing to the sys interface. Those were the update, alarm and periodic interrupts. As a side effect of the new implementation, any interrupt generated in the rtc-test driver would trigger the same code path in the generic code, and thus the distinction among interrupts gets lost. This patch preserves the previous behaviour of the rtc-test driver, where e.g. an update interrupt would not trigger an alarm or periodic interrupt, and vice-versa. In real world RTC drivers, this is not an issue, but in the rtc-test driver it may be interesting to distinguish these interrupts for testing purposes.

2011-02-03RTC: Convert rtc drivers to use the alarm_irq_enable methodJohn Stultz
Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!

2009-06-19rtc: make rtc_update_irq callable with irqs enabledAtsushi Nemoto
The rtc_update_irq() might be called with irqs enabled, if a interrupt handler was registered without IRQF_DISABLED. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock. Also update kerneldoc and drivers which do extra work to follow the current interface spec, as suggestted by David Brownell.

2009-01-06rtc: use set_mmss when set_time is not availableAlessandro Zummo

2006-11-25[PATCH] rtc class locking bugfixesDavid Brownell
I got a lockdep warning when running "rtctest" so I though it'd be good to see what was up. - The warning was for rtc->irq_task_lock, gotten from rtc_update_irq() by irq handlerss ... but in a handful of other cases, grabbed without blocking IRQs. - Some callers to rtc_update_irq() were not ensuring IRQs were blocked, yet the routine expects that; make sure all callers block IRQs. It would appear that RTC API tests haven't been part of anyone's kernel regression test suite recently, at least not with lockdep running.
