Synopsys HSDK clock controller generates and supplies clocks to various controllers and peripherals within the SoC. Each clock has assigned identifier and client device tree nodes can use this identifier to specify the clock which they consume. All available clocks are defined as preprocessor macros in the dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device tree sources.

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.

The clock subsystem adds a small amount of overhead to the image.
|
|
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
|
|
used as U-Boot proper.
