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