  35           Please note, that by default SmartReflex is only

  37           compensation for vdd mpu and vdd core from user space,

  41           Optionally autocompensation can be enabled in the kernel

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

  79           Select this option if you want to enable the OMAP 32KHz timer.
  80           This timer saves power compared to the OMAP_MPU_TIMER, and has
  81           support for no tick during idle. The 32KHz timer provides less
  82           intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
  83           currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
  84
  85           On OMAP2PLUS this value is only used for CONFIG_HZ and
  86           CLOCK_TICK_RATE compile time calculation.
  87           The actual timer selection is done in the board file
  88           through the (DT_)MACHINE_START structure.
