| description: | |
| This is a part of device tree bindings for Samsung S3C/S5P/Exynos SoC pin |
| controller. |
| |
| Pin group settings (like drive strength, pull up/down) are available as |
| macros in include/dt-bindings/pinctrl/samsung.h. |
| |
| 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). |
| |
