James" This series adds an algorithm for an I2C master physically located on an FSI slave device. The I2C master has multiple ports, each of which may be connected to an I2C slave. Access to the I2C master registers is achieved over FSI bus. Due to the multi-port nature of the I2C master, the driver instantiates a new I2C adapter for each port connected to a slave. The connected ports should be defined in the device tree under the I2C master device. Edward A.
