| help |
| 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. |

| bool "Enable clock support in SPL" |
| depends on CLK |
| help |
| 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. |
