Now I remember why I did this. COMMON_CLK wasn't an option users can select, because it is a bool and only selected by some platforms. I think it should be a tristate so one can build a driver with it. When it is selected, some drivers are built, either into kernel or as modules, up to user's choice. They are needed by common clock framework. I should add explanation in commit message. Or separate it into an individual patch. Which one is preferred?
