+``V4L2_CID_HDR_MODE (menu)``
+ Change the sensor HDR mode. A HDR picture is obtained by merging two
+ captures of the same scene using two different exposure periods. HDR mode
+ describes the way these two captures are merged in the sensor.
+
+ As modes differ for each sensor, menu items are not standardized by this
+ control and are left to the programmer.

Add V4L2_CID_HDR_MODE as a menu item control to set the HDR mode of the sensor, and its documentation. Menu items are not standardized as they differ for each sensors.
