These aren't new APIs, the clock API has been around since forever.
I disagree. When I say clock API, I mean the actual functions and their semantics. Not the existence of a header file.
The meaning of clk_enable/disable has been changed and they won't work without calling clk_prepare/unprepare. So, these are definitely new APIs. If it weren't new APIs, then none of the general drivers would need to change.
clk_prepare() and clk_unprepare() are already there for any clk.h user and are stubbed in no matter what, they're really not a meaningful barrier here.
