Enable the active pullup for the 1-Wire bus.
|
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
This property is required. |
|
|
Pin configuration/s for the second state. See pinctrl-0.
|
|
|
Pin configuration/s for the third state. See pinctrl-0.
|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|
Pin configuration/s for the fifth state. See pinctrl-0.
|
|
|
Names for the provided states. The number of names needs to match the
number of states.
This property is required. |
|
|
Set this field to enable the internal pullup resistor.
0 - Internal pullup disabled.
1 - Internal pullup enabled.
This property is required. Legal values: |
|
|
Set this field to enable the external pullup.
0 - Pullup pin is active high when enabled.
1 - Pullup pin is active low when enabled.
2 - Pullup pin is not used for an external pullup.
Legal values: |
|
|
Long Line Mode Enable
Selects alternate timings for 1-Wire communication.
The recommended setting depends on the length of the wire.
For lines less than 40 meters, 0 should be used.
Setting this bit to 0 leaves the write one release,
the data sampling, and the time-slot recovery times at
approximately 5us (micro second), 15us, and 7us, respectively.
Setting this bit to 1 enables long line mode timings during standard mode communications.
This mode moves the write one release, the data sampling,
and the time-slot recovery times out to approximately 8us, 22us, and 14us, respectively.
0 - Standard operation for lines less than 40 meters.
1 - Long Line mode enabled.

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.
