* rtc-cmos: fix wakeup from S5 without CONFIG_PM_SLEEPDaniel Glöckner2014-10-141-1/+4
| | | | | | | | | | | | | | | | Commit b5ada4600dfd ("drivers/rtc/rtc-cmos.c: fix compilation warning when !CONFIG_PM_SLEEP") broke wakeup from S5 by making cmos_poweroff a nop unless CONFIG_PM_SLEEP was defined. Fix this by restricting the #ifdef to cmos_resume and restoring the old dependency on CONFIG_PM for cmos_suspend and cmos_poweroff.

| | | | | | | | | | | | | | As pointed out by Sergei Shtylyov, the pcf8563_irq function contains a bug in the error handling: an interrupt handler is not supposed to return an errno value but an 'enum irqreturn'.

| | | | | | | | | | | | | | | | | | | | | | | | gcc-4.9 found a potential condition under which the 'pending' variable may be used uninitialized: drivers/rtc/rtc-pcf8563.c: In function 'pcf8563_irq': drivers/rtc/rtc-pcf8563.c:173:5: warning: 'pending' may be used uninitialized in this function [-Wmaybe-uninitialized] This is because in the pcf8563_get_alarm_mode() function, we check any nonzero return of pcf8563_read_block_data, but in the irq function we only check for negative values, so a possible positive value does not get detected if the compiler chooses not to inline the entire call chain. Checking for any non-zero value in the interrupt handler as well is just as correct and lets the compiler know what we are doing, without needing a bogus initialization.

* rtc: max77686: fail to probe if no RTC regmap irqchip is setJavier Martinez Canillas2014-10-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | | The max77686 mfd driver adds a regmap IRQ chip which creates an IRQ domain that is used to map the virtual RTC alarm1 interrupt. The RTC driver assumes that this will always be true since the PMIC IRQ is a required property according to the max77686 DT binding doc. If an "interrupts" property is not defined for a max77686 PMIC, then the mfd probe function will fail and the RTC platform driver will never be probed. But even when it is not possible to probe the rtc-max77686 driver without a regmap IRQ chip, it's better to explicitly check if the IRQ chip data is not NULL and gracefully fail instead of getting an OOPS.

* rtc: max77686: remove dead code for SMPL and WTSRJavier Martinez Canillas2014-10-141-101/+0
| | | | | | | | | | | | | | | | | | | | The MAX77686 RTC chip has two features called SMPL (Sudden Momentary Power Loss) and WTSR (Watchdog Timeout and Software Resets). Support for these features seems to be implemented in the driver but compilation is disabled using a C pre-processor conditional. This code has been disabled since the driver was original merged in commit fca1dd031a28 ("rtc: max77686: add Maxim 77686 driver"). So, since this code has never been built, let's just remove it.

* rtc: max77686: Allow the max77686 rtc to wakeup the systemDoug Anderson2014-10-141-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This series add support for the Real Time clock present in the Maxim 77802 Power Managment IC. The version number is quite high because it previously was part of a bigger series [0] that aimed to add support for all the devices in the max77802 PMIC. But now that the max77802 dependencies were already merged for 3.17, the series were split but I kept the version numbering. While working on the max77802 rtc support a lot of feedback was given and the issues pointed out also apply to a driver for a similar PMIC RTC (max77686). So patches 01/06 to 05/06 in the series are cleanups for the max77686 driver and patch 06/06 adds the support for the max77802 RTC. The series were tested on an Exynos5250 Snow (max77686) and Exynos5420 Peach Pit (max77802) machines. This patch (of 6): The max77686 includes an RTC that keeps power during suspend. It's convenient to be able to use it as a wakeup source.

This was observed with the driver enabled on x86 on some Fujitsu system (with possibly not up to date firmware, but anyway). Perhaps efi_read_alarm() should not fail if neither enabled nor pending are set, but the returned time is invalid?
