Subject: [PATCH v3 05/11] media: v4l2-ctrls: Add camera location and rotation
Date: Thu, 12 Sep 2019 22:10:49 +0200
Message-ID: <20190912201055.13964-6-jacopo@jmondi.org> (raw)
In-Reply-To: <20190912201055.13964-1-jacopo@jmondi.org>

Add support for the newly defined V4L2_CID_CAMERA_SENSOR_LOCATION
and V4L2_CID_CAMERA_SENSOR_ROTATION read-only controls used to report
the camera device mounting position and orientation respectively.
