What do "d0" and "d2" refer to?

This seems to indicate you have too much clock detail in the DT (with 
individual clocks described) or not enough with genericish compatible 
strings. What happens for the mext clock you need to adjust the flags 
on? You should be able to make these adjustments without DT updates. 
Perhaps you need a wider fixing of clock compatible strings.
