This doesn't apply cleanly to Mike's tree.  Can you add it to your
tree and send it out for 3.16?  Mike said you should add his Ack and
I've confirmed that the patch applies cleanly to the most recent
linuxnext (next-20140606) as well as to the top of your
'samsung-clk-next' tree (2ce16c5 clk: samsung: exynos3250: Add clocks
using common clock framework).

Thanks!
