These property descriptions apply to “nxp,imx8ulp-pinctrl” nodes themselves. This page also describes child node properties in the following sections.

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 “nxp,imx8ulp-pinctrl” compatible.

Name	Type	Details
`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
`label`	`string`	No description provided for this label See Important properties for more information.
`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
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.

Grandchild node properties

Name	Type	Details
`pinmux`	`phandles`	This property is required.
`drive-strength`	`string`	Used to configure the pad's drive strength, which, together with the slew rate, affects the maximum frequency the pad's output buffer can yield. If "normal" drive strength is used, the maximum frequency will be lower as per the measurements found in the SoC datasheet. Note that the TRM refers to the "normal" drive strength as "standard". If unspecified, the default will be "normal". Legal values: `'normal'`, `'high'`
`slew-rate`	`string`	Used to configure the pad's slew rate, which affects the maximum frequency the pad's output buffer can yield ( "fast" slew rate -> higher pad frequency, "slow" slew rate -> lower pad frequency). Note that the TRM refers to the "fast" slew rate as "standard". If unspecified, the default will be "fast". Legal values: `'fast'`, `'slow'`
`bias-pull-up`	`boolean`	enable pull-up resistor
`bias-pull-down`	`boolean`	enable pull-down resistor
`drive-open-drain`	`boolean`	drive with open drain (hardware AND)
