/** * @axis_align - controls parameters that are useful in system prototyping * and bring up. * @max_x - The maximum X coordinate that will be reported by this sensor. * @max_y - The maximum Y coordinate that will be reported by this sensor. * @nbr_fingers - How many fingers can this sensor report? * @data_pkt - buffer for data reported by this sensor. * @pkt_size - number of bytes in that buffer. * @attn_size - Size of the HID attention report (only contains abs data). * position when two fingers are on the device. When this is true, we * assume we have one of those sensors and report events appropriately. * @sensor_type - indicates whether we're touchscreen or touchpad. * @input - input device for absolute pointing stream * @input_phys - buffer for the absolute phys name for this sensor.
