Hi Benoit,

Should I re-post this patch for 3.13 or do you think that the clean-up
is not worth it due the high probability to lead to a merge conflict?

I know is an intrusive change but a needed cleanup IMHO. People keep
doing copy & paste with current am33xx DT and keep duplicating device
nodes already existing in the included .dtsi file. I reviewed at least
2 new DTS that had the same issue.

Also, this shouldn't had happened if all the OMAP DT patches went
through your tree...
