   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.

  13 config SPL_CLK
  14         bool "Enable clock support in SPL"
  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.

  23 config TPL_CLK
  24         bool "Enable clock support in TPL"
  25         depends on CLK && TPL_DM
  26         help
  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
  31           used as U-Boot proper.

  38           This clock driver adds support for enabling and disabling peripheral
  39           clocks on BCM6345 SoCs. HW has no rate changing capabilities.

  54           This clock driver adds support for RCC clock management
  55           for STM32F4 and STM32F7 SoCs.

  63           Zynq platform.
