It contains: - Small changes in mlxsw core code, needed for I2C bus support; - I2C driver, which obtains I2C input/output mailboxes setting and provides command interface implementation. - Minimal driver, which works on top of I2C driver and allows running of mlxsw command interface over I2C bus; Use case: On system, which does not have PCI to ASIC (BMC), hwmon functionality (sensors, pwm, tacho) will be available through I2C. Usage (manual probing): echo mlxsw_minimal 0x48 > /sys/bus/i2c/devices/i2c-2/new_device Sysfs interface: /sys/bus/i2c/devices/2-0048/hwmon/hwmon5/pwm1 /sys/bus/i2c/devices/2-0048/hwmon/hwmon5/temp1_input ==================== Signed-off-by: David S.
