  49. This option saves power, but assumes all drivers are
  50. using the clock framework. Broken drivers that do not
  51. yet use clock framework may not work with this option.

  68. This timer saves power compared to the OMAP_MPU_TIMER, and has
  69. support for no tick during idle. The 32KHz timer provides less
  70. intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
  71. currently only available for OMAP16XX, 24XX, 34XX, OMAP4/5 and DRA7XX.
  72. On OMAP2PLUS this value is only used for CONFIG_HZ and

  74. The actual timer selection is done in the board file
  75. through the (DT_)MACHINE_START structure.
