2018-03-01rtc: stop validating rtc_time after rtc_time64_to_tmAlexandre Belloni1-1/+1
rtc_time64_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2015-04-03drivers/rtc/ab3100: Update driver to address y2038/y2106 issuesXunlei Pang1-28/+27
This driver has a number of y2038/y2106 issues. This patch resolves them by: - Replacing rtc_tm_to_time() with rtc_tm_to_time64() - Replacing rtc_time_to_tm() with rtc_time64_to_tm() - Changing ab3100_rtc_set_mmss() to use rtc_class_ops's set_mmss64() After this patch, the driver should not have any remaining y2038/y2106 issues.

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>
2013-07-03drivers/rtc/rtc-ab3100.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.

2013-07-03rtc: rtc-ab3100: remove unnecessary platform_set_drvdata()Jingoo Han1-1/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata = NULL when no driver is bound"). Thus, it is not needed to manually clear the device driver data to NULL.

2013-04-29rtc: rtc-ab3100: use devm_rtc_device_register()Jingoo Han1-5/+2
devm_rtc_device_register() is device managed and makes cleanup paths simpler. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-04-29rtc: rtc-ab3100: use module_platform_driver_probe()Jingoo Han1-13/+1
Use module_platform_driver_probe() macro which makes the code smaller and simpler.

ab3100_rtc_probe() Otherwise, calling platform_get_drvdata() in ab3100_rtc_remove() returns NULL.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin1-23/+16
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

2010-05-28mfd: Renamed ab3100.h to abx500.hLinus Walleij1-1/+1
The goal here is to make way for a more general interface for the analog baseband chips ab3100 ab3550 ab550 and future chips. This patch have been divided into two parts since both changing name and content of a file is not recommended in git.

2009-09-17rtc: AB3100 RTC supportLinus Walleij1-0/+281
This adds support for the RTC found inside the AB3100 Mixed Signal chip. The symbols used for communicating with the chip is found in the mfd/ab3100-core.c driver that also provides the platform device.
