This allows drivers to be provided for clock generators, including
|
|
|
|
oscillators and PLLs. Devices can use a common clock API to request
|
|
|
|
a particular clock rate and check on available clocks. Clocks can
|
|
|
|
feed into other clocks in a tree structure, with multiplexers to
|
|
|
|
choose the source for each clock.

If this is acceptable and you have a need to use clock drivers in

SPL, enable this option. It might provide a cleaner interface to

setting up clocks within SPL, and allows the same drivers to be

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