  32           Say Y if you want to reset unused clocks during boot.
  33           This option saves power, but assumes all drivers are
  34           using the clock framework. Broken drivers that do not
  35           yet use clock framework may not work with this option.
  36           If you are booting from another operating system, you
  37           probably do not want this option enabled until your
  38           device drivers work properly.

  45           Pin multiplexing support for OMAP boards. If your bootloader
  46           sets the multiplexing correctly, say N. Otherwise, or if unsure,

  63           to change the pin multiplexing setup.  When there are no warnings
  64           printed, it's safe to deselect OMAP_MUX for your product.
