The internal RTC doesn't work, loading the driver only yields
rtc-mv f1010300.rtc: internal RTC not ticking
. So disable it.

You could also use the aliases to ensure rtc0 is the s35390a. This would
solve the initial issue.

What do you assume is my initial issue? Adding the alias doesn't make
the above message disappear from the boot log.

I overlooked that the rtc is not working at all (and I thought it only
needed some init in u-boot like the armada38x). Seems good to me then.

Hi Uwe
This should probably go via the mvebu maintainers, who look after the
DT files.
