If you want to use "clock-names", you have to specify the exact names
of the clock input signals used by your device, and the order in which
they are listed.

For both the clocks and the gpios, you have to specify how many signals
there are, and ideally describe what they are used for. In case of a
gpio controlling the signal level, it may be better to model this
as a gpio-regulator device, depending on how exactly it is used.
