With calling dev_pm_set_wake_irq() to set SNVS RTC as wakeup source for suspend, generic wake irq mechanism will automatically enable it as wakeup source when suspend, then the suspend/resume callback which are ONLY for enabling/disabling irq wake can be removed, it simplifies the code.

The IRQ mapping was changed to not being created in the rtc-mt6397 driver, so the irq_dispose_mapping is no longer needed. Also the dev_id passed to free_irq should be the same as the last argument passed to request_threaded_irq. This prevents a "Trying to free already-free IRQ 274" warning when unbinding the driver. Fixes: e695d3a0 ("mfd: mt6397: Create irq mappings in mfd core driver") Signed-off-by:

The SH RTC is a BCD RTC with some version having 4 digits for the year. The range for the RTCs with only 2 digits for the year was unfortunately shifted to handle 1999 to 2098. Reviewed-by:

The IRQ is requested before the struct rtc is allocated and registered, but this struct is used in the IRQ handler. This may lead to a NULL pointer dereference. Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc struct before requesting the IRQ. Reviewed-by:

There is no point in resetting the time to epoch as this means that userspace will never get the valuable information that time is actually invalid. Reviewed-by:
