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.
