I think the order of changes is a little bit off here:
 - patch 1 will break all exynos4-based boards (what about bisects?)
 - patch 2 will be still broken until all related drivers get converted to 
use clk_prepare(_enable) and clk_(disable_)unprepare.

Shouldn't the order be exactly opposite, i.e.:
 - all the patches for prepare/unprepare first
 - then the patch adding common clock frameworks support for exynos4 
(disabling the old clock code)
 - and finally the patch removing remaining (disabled by previous patch) 
code.

Also, I assume that these patches doesn't consider native device tree 
support (without auxdata, using OF-based clock lookup), correct me if I'm 
wrong. If I'm right, since Exynos SoCs are going to be DT-only, is there 
really a point for adding common clock framework support for non-DT 
platforms (which are going to be eventually dropped anyway)?
