Vendor: Nordic Semiconductor

Description

nRF PWM

Properties

Properties not inherited from the base binding file.

Name

Type

Details

center-aligned

boolean

Set this to use center-aligned (up and down) counter mode.

ch0-pin

int

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.

The channel 0 pin to use.

For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for channel 0, set:

    ch0-pin = <16>;

For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for channel 0, set:

    ch0-pin = <34>;  /* 32 + 2 */

ch0-inverted

boolean

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.
When the pin control driver is enabled, use the "nordic,invert" property
in the corresponding pin configuration group instead.

Set this to invert channel 0.

ch1-pin

int

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.

The channel 1 pin to use. The pin numbering scheme is the same
as the ch0-pin property's.

ch1-inverted

boolean

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.
When the pin control driver is enabled, use the "nordic,invert" property
in the corresponding pin configuration group instead.

Set this to invert channel 1.

ch2-pin

int

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.

The channel 2 pin to use. The pin numbering scheme is the same
as the ch0-pin property's.

ch2-inverted

boolean

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.
When the pin control driver is enabled, use the "nordic,invert" property
in the corresponding pin configuration group instead.

Set this to invert channel 2.

ch3-pin

int

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.

The channel 3 pin to use. The pin numbering scheme is the same
as the ch0-pin property's.

ch3-inverted

boolean

IMPORTANT: This option will only be used if the new pin control driver
is not enabled. It will be deprecated in the future.
When the pin control driver is enabled, use the "nordic,invert" property
in the corresponding pin configuration group instead.

Set this to invert channel 3.

#pwm-cells

int

Number of items to expect in a pwm specifier

This property is required.

Constant value: 3

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

pinctrl-1

phandles

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

pinctrl-2

phandles

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

pinctrl-3

phandles

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

pinctrl-4

phandles

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

pinctrl-names

string-array

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

Specifier cell names
