manual and these values are programmed as-is into the pin pull up/down and
driver strength register of the pin-controller.
- See also include/dt-bindings/pinctrl/samsung.h with useful constants.

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

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.
