1 | config CLK |
2 | bool "Enable clock driver support" | |
3 | depends on DM | |
4 | help | |
5 | This allows drivers to be provided for clock generators, including | |
6 | oscillators and PLLs. Devices can use a common clock API to request | |
7 | a particular clock rate and check on available clocks. Clocks can | |
8 | feed into other clocks in a tree structure, with multiplexers to | |
9 | choose the source for each clock. | |

12 | bool "Enable clock support in SPL" | |
13 | depends on CLK | |
14 | help | |
15 | The clock subsystem adds a small amount of overhead to the image. | |
16 | If this is acceptable and you have a need to use clock drivers in | |
17 | SPL, enable this option. It might provide a cleaner interface to | |
18 | setting up clocks within SPL, and allows the same drivers to be | |
19 | used as U-Boot proper. |
