+Subject: [PATCH] media: v4l2-ctrl: Document
+ V4L2_CID_CAMERA_ORIENTATION
+
+Add documentation for the V4L2_CID_CAMERA_ORIENTATION camera
+control. The newly added read-only control reports the camera device
+orientation relative to the usage orientation of the system the camera
+is installed on.

++``V4L2_CID_CAMERA_ORIENTATION (menu)``
++    This read-only control describes the camera orientation by reporting its
++    mounting position on the device where the camera is installed. The control
++    value is constant and not modifiable by software. This control is
++    particularly meaningful for devices which have a well defined orientation,
++    such as phones, laptops and portable devices since the control is expressed
++    as a position relative to the device's intended usage orientation. For
++    example, a camera installed on the user-facing side of a phone, a tablet or
++    a laptop device is said to be have ``V4L2_CAMERA_ORIENTATION_FRONT``
++    orientation, while a camera installed on the opposite side of the front one
++    is said to be have ``V4L2_CAMERA_ORIENTATION_BACK`` orientation. Camera
++    sensors not directly attached to the device, or attached in a way that
++    allows them to move freely, such as webcams and digital cameras, are said to
++    have the ``V4L2_CAMERA_ORIENTATION_EXTERNAL`` orientation.
