└─>Device Drivers
└─>COMMON_CLK
In linux kernel since version 3.1 (release Date: 2011-10-24)  
The common clock framework is a single definition of struct
clk, useful across many platforms, as well as an
implementation of the clock API in include/linux/clk.h.
Architectures utilizing the common struct clk should select
this option.
