CONFIG_KEYBOARD_GPIO_POLLED: Polled GPIO buttons

General informations

The Linux kernel configuration item CONFIG_KEYBOARD_GPIO_POLLED:

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.
