Subject[PATCH v4 0/2] input: misc: Add IBM Operation Panel driver
Date
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 v3:
- Document linux,keycodes property
- Use linux,keycodes property to map the buttons
- Put the checksumming in a seperate function
- Don't do unneccessary input_unregister calls
- Minor cleanup and add debug data to dev_dbg calls

Changes since v2:
- Add "additionalProperties: false" to dts doc
- Refactor switch statement in the input driver; check command size and call
the processing function within the STOP case
- Use a different definition name for Aspeed interrupt status mask

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
