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



.. code-block:: none

   Cypress PSoC-6 Pinctrl container node

   The Cypress PSoC-6 pins implements following pin configuration option:

     * bias-pull-up
     * bias-pull-down
     * drive-open-drain
     * drive-open-source
     * drive-push-pull   (strong)
     * input-enable      (input-buffer)

   These options define devicetree flags that are converted to SoC flags at
   CY_PSOC6_PIN_FLAGS().

                wake up the system.
