  3. bool "Enable clock driver support"
  4. depends on DM
  5. help
  6. This allows drivers to be provided for clock generators, including
  7. oscillators and PLLs. Devices can use a common clock API to request
  8. a particular clock rate and check on available clocks. Clocks can
  9. feed into other clocks in a tree structure, with multiplexers to
  10. choose the source for each clock.

  14. help
  15. The clock subsystem adds a small amount of overhead to the image.
  16. If this is acceptable and you have a need to use clock drivers in
  17. SPL, enable this option. It might provide a cleaner interface to
  18. setting up clocks within SPL, and allows the same drivers to be
  19. used as U-Boot proper.

  67. bool "Enable clock driver for Intel x86"
  68. depends on CLK && X86
  69. help
  70. This provides very basic support for clocks on Intel SoCs. The driver
  71. is barely used at present but could be expanded as needs arise.
  72. Much clock configuration in U-Boot is either set up by the FSP, or
  73. set up by U-Boot itself but only statically. Thus the driver does not
  74. support changing clock rates, only querying them.
