The probelms I see is, that with the clock patches, I'm not able to
boot into a initramfs [1].
Whereas if I just comment topckgen and preicfg in the dts, I'm able to
get the a serial console of my initramfs [2].

I wonder if you are able to get serial console from the initramfs with
the clock patches + dts patch?

Cheers,
Matthias
