Samsung pinctrl drivers changes for v6.1 1. Minor fix in order of initializing pinctrl driver - GPIOs should be configured before registering gpiolib. 2. Final steps to deprecated bindings headers with register constants. The constants were moved to include files in DTS directories, because these are not suitable for bindings. Remove final references and mark binding header as deprecated to warn any users.

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).
