Patches 1-3 can go into the clk tree. 4-6 should go through their
respective trees.

If you want I can take 7 & 8 through the clk tree.

Alternatively I can provide patches 1-3 in a separate stable topic
branch for you to pull in as a dependency. We'll both merge that stable
topic branch into our trees and you can make a note of it for the
arm-soc folks.

Mike
