Use SPDX-License-Identifier instead of a verbose license text. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

2019-04-12rtc: lpc32xx: switch to rtc_time64_to_tm/rtc_tm_to_time64Alexandre Belloni
Call the 64bit versions of rtc_tm time conversion now that the range is enforced by the core. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2019-04-12rtc: lpc32xx: simplify IRQ setupAlexandre Belloni

This allows further improvement of the driver. 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.

2018-03-01rtc: stop validating rtc_time after rtc_time_to_tmAlexandre Belloni
rtc_time_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2016-01-11rtc: lpc32xx: remove irq > NR_IRQS check from probe()Vladimir Zapolskiy
If the driver is used on an ARM platform with SPARSE_IRQ defined, semantics of NR_IRQS is different (minimal value of virtual irqs) and by default it is set to 16, see arch/arm/include/asm/irq.h. This value may be less than the actual number of virtual irqs, which may break the driver initialization. The check removal allows to use the driver on such a platform, and, if irq controller driver works correctly, the check is not needed on legacy platforms.

2014-10-20rtc: drop owner assignment from platform_driversWolfram Sang
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>
2014-04-03rtc: rtc-lpc32xx: remove unnecessary OOM messagesJingoo Han
The site-specific OOM messages are unnecessary, because they duplicate the MM subsystem generic OOM message. 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>
2013-09-11rtc: simplify devm_request_mem_region/devm_ioremapJulia Lawall
Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

2013-07-03rtc: rtc-lpc32xx: remove unnecessary platform_set_drvdata()Jingoo Han
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.

2013-01-03Drivers: 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.

2012-03-23drivers/rtc: remove IRQF_DISABLEDYong Zhang
Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts disabled") we run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled - see commit b738a50a2026 ("genirq: warn when handler enables interrupts"). So now this flag is a NOOP and can be removed.
