CONFIG_GPIO_BY_PINCTRL: GPIO support based on a pure pin control backend

General informations

The Linux kernel configuration item CONFIG_GPIO_BY_PINCTRL:

• prompt: GPIO support based on a pure pin control backend
• type: tristate
• depends on: CONFIG_GPIOLIB
• defined in drivers/gpio/Kconfig
• found in Linux kernels: 7.1-rc+HEAD
• modules built: gpio-by-pinctrl

Help text

Support for generic GPIO handling based on top of pin control. Traditionally, firmware creates a GPIO interface or a pin controller interface and we have a driver to support it. But in SCMI, the pin control interface is generic and we can create a simple GPIO device based on the pin control interface without doing anything custom.

This driver is used to access GPIOs over the ARM SCMI protocol.
