  60           Say Y if you want to reset unused clocks during boot.
  61           This option saves power, but assumes all drivers are
  62           using the clock framework. Broken drivers that do not
  63           yet use clock framework may not work with this option.
  64           If you are booting from another operating system, you
  65           probably do not want this option enabled until your
  66           device drivers work properly.
