This series adds support for input from the IBM Operation Panel, which is
a simple controller with three buttons and an LCD display meant for
interacting with a server. It's connected over I2C. This series only
supports the input from the panel, in which the panel masters the I2C bus
and sends data to the host system when someone presses a button on the
controller.
