TI tmp1075 driver implemented based on tmp108 driver. The driver initializes the sensor based on the DTS. Added tmp1075 example overlay file to thermometer sample. All you need to do to use the sensor is to connect the I2C and optionally interrupt line. To see default DTS configuration option inspect `ti,tmp1075.yaml` bindings file and sensor spec.
