Can you please make the commit message more detailed, explaining why you're
making this change; what it adds/fixes/removes/etc.? Right now just reading this
I'm unclear as to why you're adding a call to device_init_wakeup() here. The
generic I2C client code will mark the parent MFD device as a wake source, if
the relevant boolean 'wakeup' is defined in DT, so what does this add?

v1->v2:
Alexandre Belloni:

Dropped everything except device_init_wakeup, as driver refuses to load
without irq specified, we can always set it as a wakeup source, before
calling devm_rtc_register_device.
