pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

clock-source

string

Select one of three possible clock sources for the FTM counter:
  * system: it's the bus interface clock driving the FTM module. Usually
    provides higher timer resolution than the other two clock sources.
  * fixed: it's a fixed clock defined by chip integration.
  * external: it's a clock that can be accessed externally to the chip and
    passes through a sychronizer clocked by the FTM bus interface clock.

This clock source selection is independent of the bus interface clock
driving the FTM module. Refer to the chip specific documentation for
further information.

This property is required.

Legal values: 'system', 'fixed', 'external'
