drivers/rtc/rtc-ds1685.c: fix conditional in ds1685_rtc_sysfs_time_regs_{show,store}

2015-02-28T17:57:51Z

Fix a conditional statement checking for NULL in both ds1685_rtc_sysfs_time_regs_show and ds1685_rtc_sysfs_time_regs_store that was using a logical AND when it should be using a logical OR so that we fail out of the function properly if the condition ever evaluates to true.

rtc: ds1685: fix ds1685_rtc_alarm_irq_enable build error

2015-02-28T17:57:51Z

The newly added ds1685 driver causes a build error when enabled without CONFIG_RTC_INTF_DEV: drivers/rtc/rtc-ds1685.c:919:22: error: 'ds1685_rtc_alarm_irq_enable' undeclared here (not in a function) .alarm_irq_enable = ds1685_rtc_alarm_irq_enable, Apparently the driver was incorrectly changed to reflect the interface change from 16380c153a69c ("RTC: Convert rtc drivers to use the alarm_irq_enable method"), which removed the respective #ifdef from all other rtc drivers. This does the same change that was merged for the other drivers before and removes the #ifdef, allowing the interrupts to be enabled through the in-kernel rtc interface independent of the existence of /dev/rtc.

Pull kconfig updates from Michal Marek: "Yann E Morin was supposed to take over kconfig maintainership, but this hasn't happened. So I'm sending a few kconfig patches that I collected: - Fix for missing va_end in kconfig - merge_config.sh displays used if given too few arguments - s/boolean/bool/ in Kconfig files for consistency, with the plan to only support bool in the future" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kconfig: use va_end to match corresponding va_start merge_config.sh: Display usage if given too few arguments kconfig: use bool instead of boolean for type definition attributes

rtc: add driver for DS1685 family of real time clocks

2015-02-17T01:56:05Z

This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287, DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly found in SGI O2 and SGI Octane systems. It was originally derived from a driver patch submitted by Matthias Fuchs many years ago for use in EPPC-405-UC modules, which also used these RTCs. In addition to the time-keeping functions, this RTC also handles the shutdown mechanism of the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these systems. Verified on both an SGI O2 and an SGI Octane. Signed-off-by: Joshua Kinard Cc: Ralf Baechle Cc: Alessandro Zummo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rtc: isl12057: deprecate use of isl in compatible string for isil

2015-02-17T01:56:02Z

"isil" and "isl" prefixes are used at various locations inside the kernel to reference Intersil corporation. This patch is part of a series fixing those locations were "isl" is used in compatible strings to use the now expected "isil" prefix instead (NASDAQ symbol for Intersil and most used version). The old compatible string is kept for backward compatibility.

drivers/rtc/rtc-armada38x: add a new RTC driver for recent mvebu SoCs

2015-02-14T05:21:43Z

The new mvebu SoCs come with a new RTC driver. This patch adds the support for this new IP which is currently found in the Armada 38x SoCs. This RTC provides two alarms, but only the first one is used in the driver. The RTC also allows using periodic interrupts.

rtc: rtc-ab-b5ze-s3: add sub-minute alarm support

2015-02-14T05:21:43Z

Abracon AB-RTCMC-32.768kHz-B5ZE-S3 alarm is only accurate to the minute. For that reason, UIE mode is currently not supported by the driver. But the device provides a watchdog timer which can be coupled with the alarm mechanism to extend support and provide sub-minute alarm capability. This patch implements that extension. More precisely, it makes use of the watchdog timer for alarms which are less that four minutes in the future (with second accuracy) and use standard alarm mechanism for other alarms (with minute accuracy).
