Expected external clocks, defined in DTS as fixed-rate clocks with a matching
|
|
name::
|
|
- "fin_pll" - PLL input clock from XXTI
|
|
|
|
All available clocks are defined as preprocessor macros in
|
|
include/dt-bindings/clock/exynos5410.h header.

Should contain an entry specifying the root clock from external
|
|
oscillator supplied through XXTI or XusbXTI pin. This clock should be
|
|
defined using standard clock bindings with "fin_pll" clock-output-name.
|
|
That clock is being passed internally to the 9 PLLs.
