0016 Expected external clocks, defined in DTS as fixed-rate clocks with a matching
0017 name::
0018 - "xxti" - external crystal oscillator connected to XXTI and XXTO pins of
0019 the SoC,
0020 - "xusbxti" - external crystal oscillator connected to XUSBXTI and XUSBXTO
0021 pins of the SoC,
0022
0023 All available clocks are defined as preprocessor macros in
0024 include/dt-bindings/clock/s5pv210.h header.
