+         The common clock framework is a single definition of struct

+         implementation of the clock API in include/linux/clk.h.
+         Architectures utilizing the common struct clk should select

+         Traverses the entire clock tree and disables any clocks that are
+         enabled in hardware but have not been enabled by any device drivers.
+         This saves power and keeps the software model of the clock in line

+         Creates a directory hierchy in debugfs for visualizing the clk
+         tree structure.  Each directory contains read-only members

+         clk_flags, clk_prepare_count, clk_enable_count &
+         clk_notifier_count.
