16	  The common clock framework is a single definition of struct
17	  clk, useful across many platforms, as well as an
18	  implementation of the clock API in include/linux/clk.h.
19	  Architectures utilizing the common struct clk should select
20	  this option.

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

41	  Creates a directory hierchy in debugfs for visualizing the clk
42	  tree structure.  Each directory contains read-only members
43	  that export information specific to that clk node: clk_rate,
44	  clk_flags, clk_prepare_count, clk_enable_count &
45	  clk_notifier_count.
