nxp,imx-iomuxc
Vendor: NXP Semiconductors
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.
Properties
Top level properties
These property descriptions apply to “nxp,imx-iomuxc” nodes themselves. This page also describes child node properties in the following sections.
Properties not inherited from the base binding file.
(None)
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 “nxp,imx-iomuxc” compatible.

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

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 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. |

|
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

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.
