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

  13config SPL_CLK

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

  28          If this is acceptable and you have a need to use clock drivers in
  29          SPL, enable this option. It might provide a cleaner interface to

  39          clocks on BCM6345 SoCs. HW has no rate changing capabilities.

  77        bool "Enable clock driver for Intel x86"
  78        depends on CLK && X86
  79        help
  80          This provides very basic support for clocks on Intel SoCs. The driver
  81          is barely used at present but could be expanded as needs arise.
  82          Much clock configuration in U-Boot is either set up by the FSP, or
  83          set up by U-Boot itself but only statically. Thus the driver does not
  84          support changing clock rates, only querying them.

  98          This enables the clock driver support over TI System Control Interface
  99          available on some new TI's SoCs. If you wish to use clock resources
 100          managed by the TI System Controller, say Y here. Otherwise, say N.
