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

From: Eddie James
Date: Tue Sep 08 2020 - 16:01:43 EST

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
