Subject: [PATCH v2 0/5] input: misc: Add IBM Operation Panel driver

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, typically to a service
processor. 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.

Changes since v1:
 - Redo DTS documentation example to use I2C_OWN_SLAVE_ADDRESS
 - Reject commands received in the input driver that are too long
 - Add a definition for the interrupt status mask in the Aspeed I2C driver
 - Use I2C_OWN_SLAVE_ADDRESS for both dts additions
