Alexandre, I definitely agree with you on the fact that the MTK PMIC RTC driver
can (and needs to) be improved, and that it can make use of some nice cleanup...

... but!

This series performs a conversion to schema, and the previous txt file didn't
say anything about the start-year property - which was not mandatory to support
at that time (nor now, afaik?), so adding support for that is out of scope for
this series.

Eventually, that can come as a series on top, adding support for that in the
binding (and, of course, in the driver).

I should be able to tackle that... most probably next week - but still, the
improvements would come as a series on top of this one.

Cheers,
Angelo
