Oh, I just looked into my local tree from Linus (latest!) and therefore 
saw the

	s35390a->rtc->uie_unsupported = 1;

code without checking when it has been committed. That why I assumed 
that the problem is still there - even with uie_unsupported = 1 ...

Very good! So I'll wait and see when the linux-image-4.19.0-x-marvell 
kernel arrives on my two boxes ;-)

Many thanks & best regards,
