  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.

  40         ---help---
  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.
