General informations

The Linux kernel configuration item CONFIG_KEYBOARD_GPIO_POLLED:

• prompt: Polled GPIO buttons
• type: tristate
• depends on: CONFIG_GPIOLIB
• defined in drivers/input/keyboard/Kconfig
• found in Linux kernels: 2.6.37–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12

Help text

This driver implements support for buttons connected to GPIO pins that are not capable of generating interrupts.

Say Y here if your device has buttons connected directly to such GPIO pins. Your board-specific setup logic must also provide a platform device, with configuration data saying which GPIOs are used.

To compile this driver as a module, choose M here: the module will be called gpio_keys_polled.
