nordic,nrf-pwm¶

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.

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.
