|
The integral part of the divider for pwm slice 0.
If a value between 1 and 255 is set, it will be set to the register
as the integer part of the divider.
If the value is set to 0 or this property is not defined when setting
the number of cycles to PWM, a division ratio appropriate to that value is set.
|
|
|
The fractional part of the divider for pwm slice 0.
This number should be in the range 0 - 15.
When the "divider-int-0" is set to 0 or is not defined, this property will be
ignored.

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.
|
|
|
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.
|
|
|
Reset information
|
|
|
Name of each reset

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 “raspberrypi,pico-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.
|
|
|
List of power states that will disable this device power.
