I can do a review but I wonder how much it will change anyway.

This code has bugs in it, so a new patch set is required.
Here's the first set of patches that I'm working on for the Common Clk Framework. Part of this patch series adds a new clk op, pre_rate_req. This is designed to replace the clk notifier approach that many clk drivers use right now to setup alt parents or temporary dividers. This should allow for the removal of the CLK_RECALC_NEW_RATES flag and the implementation of a better locking scheme for the prepare lock.
