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 Eddie James (2): dt-bindings: input: Add documentation for IBM Operation Panel input: misc: Add IBM Operation Panel driver .../bindings/input/ibm,op-panel.yaml | 49 +++++ MAINTAINERS | 7 + drivers/input/misc/Kconfig | 18 ++ drivers/input/misc/Makefile | 1 + drivers/input/misc/ibm-panel.c | 198 ++++++++++++++++++ 5 files changed, 273 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/ibm,op-panel.yaml create mode 100644 drivers/input/misc/ibm-panel.c -- 2.27.0
