rtc: simplify implementations of read_alarm

2016-07-09T08:24:45Z

Since commit d68778b80dd7 ("rtc: initialize output parameter for read alarm to "uninitialized"") there is no need to explicitly set unsupported members to -1. So drop the respective assignments from drivers. Signed-off-by: Uwe Kleine-König Signed-off-by: Alexandre Belloni

char/genrtc: x86: remove remnants of asm/rtc.h

2016-06-03T22:20:07Z

Commit 3195ef59cb42 ("x86: Do full rtc synchronization with ntp") had the side-effect of unconditionally enabling the RTC_LIB symbol on x86, which in turn disables the selection of the CONFIG_RTC and CONFIG_GEN_RTC drivers that contain a two older implementations of the CONFIG_RTC_DRV_CMOS driver. This removes x86 from the list for genrtc, and changes all references to the asm/rtc.h header to instead point to the interfaces from linux/mc146818rtc.h.

rtc: Use IS_ENABLED() instead of checking for built-in or module

2016-05-20T10:33:51Z

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Signed-off-by: Javier Martinez Canillas Signed-off-by: Alexandre Belloni

rtc: remove use of seq_printf return value

2015-04-15T23:35:24Z

The seq_printf return value, because it's frequently misused, will eventually be converted to void. See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to seq_has_overflowed() and make public") Signed-off-by: Joe Perches Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-mrst: fix suspend/resume

2015-03-25T23:20:30Z

The Moorestown RTC driver implements suspend and resume callbacks and assigns them to the suspend and resume fields of the device_driver struct. These callbacks are never actually called by anything though. Modify the driver to properly use dev_pm_ops so that the suspend and resume functions are actually executed upon suspend/resume.

drivers/rtc/rtc-mrst.c: remove redundant dev_set_drvdata

2013-11-13T03:09:27Z

Driver core sets the driver data to NULL upon device_release or on probe failure. Signed-off-by: Sachin Kamat Cc: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

intel_mid: Renamed mrst to intel_mid

2013-10-17T23:40:36Z

Following files contains code that is common to all intel mid soc's. So renamed them as below. mrst/mrst.c -> intel-mid/intel-mid.c mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c pci/mrst.c -> pci/intel_mid_pci.c Also, renamed the corresponding header files and made changes to the driver files that included these header files. To ensure that there are no functional changes, I have compared the objdump of renamed files before and after rename and found that the only difference is file name change.

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02Z

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.

drivers/rtc: remove IRQF_DISABLED

2012-03-23T23:58:39Z

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.

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53Z

This patch converts the drivers in drivers/rtc/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.
