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

 103           This timer saves power compared to the OMAP_MPU_TIMER, and has
 104           support for no tick during idle. The 32KHz timer provides less
 105           intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
 106           currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
