SubjectRE: [PATCH v2] rtc: da9063: add as wakeup source

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?
