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.
