+ST VGXY61 camera sensor driver
+==============================
+
+The ST VGXY61 driver implements the following controls:
+
+``V4L2_CID_HDR_SENSOR_MODE``
+-------------------------------
+ Change the sensor HDR mode. A HDR picture is obtained by merging two
+ captures of the same scene using two different exposure periods.
+
+.. flat-table::
+ :header-rows: 0
+ :stub-columns: 0
+ :widths: 1 4
+
+ * - HDR linearize
+ - The merger outputs a long exposure capture as long as it is not
+ saturated.
+ * - HDR substraction
+ - This involves subtracting the short exposure frame from the long
+ exposure frame.
+ * - No HDR
+ - This mode is used for standard dynamic range (SDR) exposures.
