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.

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 “nordic,nrf-pwm” compatible.

Name

Type

Details

reg

array

register space

This property is required.

See Important properties for more information.

label

string

Human readable string describing the device (used as device_get_binding() argument)

This property is required.

See Important properties for more information.

status

string

indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

compatible

string-array

compatible strings

This property is required.

See Important properties for more information.

reg-names

string-array

name of each register space

interrupts

array

interrupts for device

See Important properties for more information.

interrupts-extended

compound

extended interrupt specifier for device

interrupt-names

string-array

name of each interrupt

interrupt-parent

phandle

phandle to interrupt controller node

clocks

phandle-array

Clock gate information

clock-names

string-array

name of each clock

#address-cells

int

number of address cells in reg property

#size-cells

int

number of size cells in reg property

dmas

phandle-array

DMA channels specifiers

dma-names

string-array

Provided names of DMA channel specifiers

io-channels

phandle-array

IO channels specifiers

io-channel-names

string-array

Provided names of IO channel specifiers

mboxes

phandle-array

mailbox / IPM channels specifiers

mbox-names

string-array

Provided names of mailbox / IPM channel specifiers

wakeup-source

boolean

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

phandle

Power domain the device belongs to.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
