Number of items to expect in a PWM
- channel of the timer used for PWM
- period to set in ns
- flags : combination of standard flags like PWM_POLARITY_NORMAL
or specific flags like STM32_PWM_COMPLEMENTARY. As an example,
the following complementary PWMs(CH2&CH2N) are shown below.
<&pwm1 2 100 (PWM_POLARITY_NORMAL)>;
<&pwm1 2 100 (PWM_POLARITY_NORMAL | STM32_PWM_COMPLEMENTARY)>;
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. |
|
|
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. |
|
|
Add support to capture on four channels. This is less accurate than
the default 2 channel support because the counter is reset by
interrupt instead of slave-mode controller. This option can also
be used as alternative for timers that does not support slave mode.
|
Deprecated properties not inherited from the base binding file.
(None)
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 “st,stm32-pwm” compatible.

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.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device
