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
14	bool "Enable clock support in SPL"
15	depends on CLK
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.
