I do agree, it should not, I made that comment into the 
board-omap4-dt.c, but for the moment we still have dedicated OMAP 
specifics stuff at board level, like the map_io.

I have an other series that make the map_io DT aware to get rid of that, 
but it still not finalized.

My goal was have a single DT_MACHINE_START for every OMAPs.
But, meanwhile, if you prefer one file with many board descriptors, 
that's fine.

Yep, I know, but since that series is based on my previous series that 
is based on mainline rc-3, I missed these.

Now, that kernel.org is back, I'll pull you branches :-).

Which one do you recommend in that case, master or cleanup?

OK, I can get rid of mux stuff then.

Cool, I'll update the whole series, including the OMAP4 ones.
