| 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. | |
