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.
