Hey Tony,
Can you retry with the branch? I just pushed one patch there, seems the
parents for the vlynq_mux_fck were somewhat broken (there are holes in
the valid mux values list, which hasn't happened with any other
mux-clock so far.)
If this works, I will rework the series a bit and send v2 out.
Alternatively I need to add extra debug info.
