| 16 | + Expected external clocks, defined in DTS as fixed-rate clocks with a matching |
| 17 | + name:: |
| 18 | + - "xxti" - external crystal oscillator connected to XXTI and XXTO pins of |
| 19 | + the SoC, |
| 20 | + - "xusbxti" - external crystal oscillator connected to XUSBXTI and XUSBXTO |
| 21 | + pins of the SoC, |
| 22 | +
|
| 23 | + All available clocks are defined as preprocessor macros in |
| 24 | + include/dt-bindings/clock/s5pv210.h header. |
