nordic,nrf-sw-pwm

Vendor: Nordic Semiconductor

Description

nRFx S/W PWM

Properties

Node specific properties

Properties not inherited from the base binding file.

Name	Type	Details
generator	phandle	Reference to TIMER or RTC instance for generating PWM output signals
channel-count	int	Number of PWM channels. Limited by RTC/TIMER instance compare registers minus 1. This property is required.
clock-prescaler	int	Clock prescaler for RTC or TIMER used for generating PWM output signals. RTC: needs to be set to 0, which gives 32768 Hz base clock for PWM generation. TIMER: 16 MHz / 2^prescaler base clock is used for PWM generation. This property is required.
ppi-base	int	PPI base used for PPI index calculation used for PWM output generation This property is required.
gpiote-base	int	GPIOTE base used for GPIOTE index calculation used for PWM output generation This property is required.
#pwm-cells	int	Number of items to expect in a pwm specifier This property is required. Constant value: 1

Deprecated node specific properties

Deprecated properties not inherited from the base binding file.

Name	Type	Details
timer-instance	int	Timer instance to use for generating the PWM output signals. Deprecated in favour of 'generator' property.

Base properties

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-sw-pwm” compatible.

Name	Type	Details
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	array	register space 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
