Gregory is in the process of dual licensing some of the other mvebu DT
files. This one is single license. Should it be dual?

Humm, ttyS0? Then why add the LL_DEBUG via UART1?

Maybe add

stdout-path = &uart1;

Is there anything on these two i2c busses? If not, why enable them and
increase the clock speed?

If it is not obvious from the silk screen, could you describe which
connector this uart is on, what pins are what?

Does this clock need enabling? Should it be listed in the clocks
property?
