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.

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.
