  * @board_info: pointer to I2C subdevice's board info
  * @clk_frequency: frequency of the clock the host interface provides to sensor
  * @bus_type: determines bus type, MIPI, ITU-R BT.601 etc.
+ * @csi_data_align: MIPI-CSI interface data alignment in bits
  * @i2c_bus_num: i2c control bus id the sensor is attached to
  * @mux_id: FIMC camera interface multiplexer index (separate for MIPI and ITU)
  * @flags: flags defining bus signals polarity inversion (High by default)
