rtc: max77686: fail to probe if no RTC regmap irqchip is set 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: Properly handle regmap_irq_get_virq() error code commit fb166ba1d7f0a662f7332f4ff660a0d6f4d76915 upstream. The regmap_irq_get_virq() can return 0 or -EINVAL in error conditions but driver checked only for value of 0. This could lead to a cast of -EINVAL to an unsigned int used as a interrupt number for devm_request_threaded_irq(). Although this is not yet fatal (devm_request_threaded_irq() will just fail with -EINVAL) but might be a misleading when diagnosing errors.

rtc: max77686: Allow the max77686 rtc to wakeup the system 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.
