2019-03-20rtc: sh: Fix invalid alarm warning for non-enabled alarmGeert Uytterhoeven
When no alarm has been programmed on RSK-RZA1, an error message is printed during boot: rtc rtc0: invalid alarm value: 2019-03-14T255:255:255 sh_rtc_read_alarm_value() returns 0xff when querying a hardware alarm field that is not enabled. __rtc_read_alarm() validates the received alarm values, and fills in missing fields when needed. While 0xff is handled fine for the year, month, and day fields, and corrected as considered being out-of-range, this is not the case for the hour, minute, and second fields, where -1 is expected for missing fields. Fix this by returning -1 instead, as this value is handled fine for all fields.

2019-03-20rtc: cros-ec: Fail suspend/resume if wake IRQ can't be configuredStephen Boyd
If we encounter a failure during suspend where this RTC was programmed to wakeup the system from suspend, but that wakeup couldn't be configured because the system didn't support wakeup interrupts, we'll run into the following warning: Unbalanced IRQ 166 wake disable WARNING: CPU: 7 PID: 3071 at kernel/irq/manage.c:669 irq_set_irq_wake+0x108/0x278 This happens because the suspend process isn't aborted when the RTC fails to configure the wakeup IRQ. Instead, we continue suspending the system and then another suspend callback fails the suspend process and "unwinds" the previously suspended drivers by calling their resume callbacks. When we get back to resuming this RTC driver, we'll call disable_irq_wake() on an IRQ that hasn't been configured for wake. Let's just fail suspend/resume here if we can't configure the system to wake and the user has chosen to wakeup with this device. This fixes this warning and makes the code more robust in case there are systems out there that can't wakeup from suspend on this line but the user has chosen to do so.
