##############

Vendor: :ref:`NXP Semiconductors <dt_vendor_nxp>`

Description
***********



.. code-block:: none

   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.

Top level properties
====================


These property descriptions apply to "nxp,imx-iomuxc"
nodes themselves. This page also describes child node
properties in the following sections.

.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      (None)

   .. group-tab:: Deprecated node specific properties

      Deprecated properties not inherited from the base binding file.

      (None)

   .. group-tab:: 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.

                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.
