| 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. |
