Hi all,

I think, basically it'd better if could control clock stuff in each driver for it when need it such as clk_get, clk_enable and so on.
Actually there is no policy/protection for EPLL usage in plat-samsung or plat-s5p now and need to sort out other similar case for it also....so in my opinion, right now to proceed with the current style is helpful to me and will consider it in the future.
