Would it be okay if we took this through the mvebu tree?  It looks like
the only potential merge conflict we would have would be in
drivers/clk/Makefile.  It would make dependency tracking easier.

Otherwise is fine as well, just let me know which you prefer.

Assuming, of course, everything looks good to you.

thx,

Jason.
