+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).
+

+ pattern: "^pinctrl(@.*)?"
