+Melexis mlx7502x ToF camera sensor driver
+=========================================
+
+The mlx7502x driver implements the following driver-specific controls:
+
+``V4L2_CID_MLX7502X_OUTPUT_MODE (menu)``
+----------------------------------------
+	The sensor has two taps, which gather reflected light: A and B.
+	The control sets the way data should be put in a buffer. The most
+	common output mode is A-B which provides the best sunlight robustness.
+
+.. flat-table::
+	:header-rows:  0
+	:stub-columns: 0
+	:widths:       1 4
+
+	* - ``(0)``
+	  - A minus B
+	* - ``(1)``
+	  - A plus B
+	* - ``(2)``
+	  - only A
+	* - ``(3)``
+	  - only B
+	* - ``(4)``
+	  - A and B (this config will change PAD format)
