Help text

This driver implements basic keypad functionality for keys connected through TCA6416/TCA6408A IO expanders.

Say Y here if your device has keys connected to TCA6416/TCA6408A IO expander. Your board-specific setup logic must also provide pin-mask details(of which TCA6416 pins are used for keypad).

If enabled the entire TCA6416 device will be managed through this driver.

To compile this driver as a module, choose M here: the module will be called tca6416_keypad.
