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



.. code-block:: none

   MCI IO MUX pin control node. This node defines pin configurations in pin
   groups, and has the 'pinctrl' node identifier in the SOC's devicetree. Each
   group within the pin configuration defines a peripheral's pin configuration.
   Each numbered subgroup represents pins with shared configuration for that
   peripheral. The 'pinmux' property of each group selects the pins to be
   configured with these properties. For example, here is a configuration
   for FLEXCOMM0 pins:

   pinmux_flexcomm0_usart: pinmux_flexcomm0_usart {
     group0 {
       pinmux = <IO_MUX_FC0_USART_DATA_IO2>,
               <IO_MUX_FC0_USART_DATA_IO3>;
       slew-rate = "normal";
     };
   };

   If only the required properties are supplied, the pin will be configured
   as normal drive strength and no pull. This corresponds to the following
   pin settings:
   PAD_PU_PD_ENx = (0x0 << pin_index)
   SR_CONFIGx = (0x2 << pin_index)

   Note

   Note the inherited pinctrl properties defined below have the following effects:
   bias-pull-up: PAD_PU_PD_ENx= (0x1 << pin_index)
   bias-pull-down: PAD_PU_PD_ENx= (0x10 << pin_index)

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


These property descriptions apply to "nxp,mci-io-mux"
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,mci-io-mux" 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.

           - .. code-block:: none


                Power domain the device belongs to.
