+Optional properties:
+- clocks: list of clock identifiers which are external input clocks to the

+ the input clocks for a given controller.
+- clock-names: list of names of clocks which are exteral input clocks to the

+Input clocks for top clock controller:
+ - sxosc (external crystal oscillator 32KHz, recommended)
+ - fxosc (external crystal oscillator 24MHz, recommended)
+ - audio_ext
+ - enet_ext
+
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/vf610-clock.h
for the full list of VF610 clock IDs.
