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

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

  86           On OMAP2PLUS this value is only used for CONFIG_HZ and

  88           The actual timer selection is done in the board file
