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.

120 help
121 This provides very basic support for clocks on Intel SoCs. The driver
122 is barely used at present but could be expanded as needs arise.
123 Much clock configuration in U-Boot is either set up by the FSP, or
124 set up by U-Boot itself but only statically. Thus the driver does not
125 support changing clock rates, only querying them.
