[Bernd Wagner]

This driver controls GAs (accessories) by the I/O ports of MCP23017 16Bit-I/O-Expanders driven by the i2c-dev interface of the Linux kernel (similar to the i2c-dev driver, but other hardware).
Read more in README.i2c-23017.
There is a graphical circuit diagram README_i2c-23017_circuit_diagram.jpeg which is referenced in the README.i2c-23017 and should be added as additional README file.
