+  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.
