Number of items to expect in a pwm specifier
This property is required. Constant value: |

|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
This property is required. |
|
|
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: |

Input clock prescaler
This property is required. Legal values: |
|
|
Pin configuration/s for the second state. See pinctrl-0.

|
Pin configuration/s for the third state. See pinctrl-0.

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

Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
Base properties
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nxp,kinetis-ftm-pwm” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
