description: |
  This is a part of device tree bindings for Samsung S3C/S5P/Exynos SoC pin
  controller.

  All the pin controller nodes should be represented in the aliases node using
  the following format 'pinctrl{n}' where n is a unique number for the alias.

  The controller supports three types of interrupts::
   - External GPIO interrupts (see interrupts property in pin controller node);

   - External wake-up interrupts - multiplexed (capable of waking up the system
     see interrupts property in external wake-up interrupt controller node -
     samsung,pinctrl-wakeup-interrupt.yaml);

   - External wake-up interrupts - direct (capable of waking up the system, see
     interrupts property in every bank of pin controller with external wake-up
     interrupt controller - samsung,pinctrl-gpio-bank.yaml).
