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.

description:
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.
