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



.. code-block:: none

   Kinetis pinctrl node. This node will define pin configurations in pin groups,
   and has the 'pinctrl' node identifier in the SOC's devicetree. Each group
   within the pin configuration defines the pin configuration for a peripheral,
   and each numbered subgroup in the pin group defines all the pins for that
   peripheral with the same configuration properties. The 'pins' property in
   a group selects the pins to be configured, and the remaining properties set
   configuration values for those pins. Here is an example group for UART0 pins:

   uart0_default: uart0_default {
     group0 {
       pins = <UART0_RX_PTB16
         UART0_TX_PTB17>;
       drive-strength = "low";
       slew-rate = "fast";
       };
   };

   If only the required properties are supplied, the pin configuration register
   will be assigned the following values:
   PCR_PS=0,
   PCR_PE=0,
   PCR_ODE=0,
   PCR_SRE=<slew-rate selection>,
   PCR_DSE=<drive-strength selection>,
   PCR_PFE=0

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


These property descriptions apply to "nxp,kinetis-pinctrl"
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,kinetis-pinctrl" 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.
