   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.

  23config TPL_CLK
  24        bool "Enable clock support in TPL"
  25        depends on CLK && TPL_DM

  27          The clock subsystem adds a small amount of overhead to the image.
  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
  30          setting up clocks within TPL, and allows the same drivers to be

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

  55          for STM32F4 and STM32F7 SoCs.
