nxp,imx-iomuxc

Description

This compatible binding should be applied to the device's iomuxc DTS node.
the DTS node will be populated with all pinmux options for the specific SOC.
These options can then be used in a pinctrl node with the "nxp,mcux-rt-pinctrl"
compatible string to define pin groups.

The user should not edit the bindings defined within this node to make pinmux
selections, but should instead edit the pinctrl groups for their board.

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 “nxp,imx-iomuxc” compatible.

Name	Type	Details
`reg`	`array`	register space 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
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`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.

Child node properties

Name	Type	Details
`pinmux`	`array`	An array of values defining the pin mux selection, in the following format: <mux_register, mux_val, input_reg, daisy_val, cfg_reg> mux_register: register that will be written to make mux selection mux_val: value to write to mux_register input_reg: peripheral register that will direct peripheral signal to pin daisy_val: value to write to input_reg cfg_reg: register that will configure pin pull, drive strength, and open drain This property is required.
`gpr`	`array`	An array of values defining the GPR bit write required, if one exists. Some IOMUXC options require writing to an IOMUXC_GPR register to select them. This array has the following elements: <gpr_reg, gpr_shift, gpr_val> gpr_reg: GPR register address to write to gpr_shift: shift to apply to value before writing gpr_val: value to write
`pin-pue`	`boolean`	RT11xx parts have multiple types of IOMUXC registers defined, with different register layouts. This property can be set to indicate to the pinctrl driver the type of register this pinmux represents, and should not be modified by the user.
`pin-pdrv`	`boolean`	RT11xx parts have multiple types of IOMUXC registers defined, with different register layouts. This property can be set to indicate to the pinctrl driver the type of register this pinmux represents, and should not be modified by the user.
`pin-lpsr`	`boolean`	RT11xx parts have multiple types of IOMUXC registers defined, with different register layouts. This property can be set to indicate to the pinctrl driver the type of register this pinmux represents, and should not be modified by the user.
`pin-snvs`	`boolean`	RT11xx parts have multiple types of IOMUXC registers defined, with different register layouts. This property can be set to indicate to the pinctrl driver the type of register this pinmux represents, and should not be modified by the user.
