23   - through mappings of XU controls to V4L2 controls
26 The first one allows generic V4L2 applications to use XU controls by mapping
27 certain XU controls onto V4L2 controls, which then show up during ordinary
42 ranges thereof to be mapped to new V4L2 controls. Such controls appear and
43 function exactly like normal V4L2 controls (i.e. the stock controls, such as
44 brightness, contrast, etc.). However, reading or writing of such a V4L2 controls
109 UVCIOC_CTRL_MAP - Map a UVC control to a V4L2 control
117 	control and a V4L2 control. Once mappings are defined, userspace
118 	applications can access vendor-defined UVC control through the V4L2
123 	UVCIOC_CTRL_ADD and a new V4L2 control.
125 	A UVC control can be mapped to several V4L2 controls. For instance,
126 	a UVC pan/tilt control could be mapped to separate pan and tilt V4L2
129 	V4L2 control.
131 	For signed integer V4L2 controls the data_type field should be set to
156 	__u32	id		V4L2 control identifier
157 	__u8	name[32]	V4L2 control name
160 	__u8	size		V4L2 control size (in bits)
161 	__u8	offset		V4L2 control offset (in bits)
163 		v4l2_type	V4L2 control type
