We came up\nwith a pretty lengthy description which I have replicated exactly here in the\nDTS property definition. The description is meant to be read by integrators\nwhich need a reference in order to properly calculate the rotation of their\ncamera modules. The property is thus expanded to be defined as the rotation\ndifference between to reference systems, precisely defined to reduce the\nrisk of having different interpretations between different camera module\nintegrators.\n\nIn the V4L2_CID_CAMERA_SENSOR_ROTATION control documentation I tried to provide\na description on how to use the control from a user point of view. The\ndescription is meant to be read by application developers, which needs to\nknow how to rotate images to compensate the camera rotation. The value of the\ncontrol is exactly the same as the property one, but described from a consumer\npoint of view.\n\nThe rest of the series is unchanged.\n\nThanks\n j\n\nJacopo Mondi (11):\n dt-bindings: video-interfaces: Document 'location' property\n media: v4l2-ctrl: Document V4L2_CID_CAMERA_SENSOR_LOCATION\n dt-bindings: video-interface: Replace 'rotation' description\n media: v4l2-ctrl: Document V4L2_CID_CAMERA_SENSOR_ROTATION\n media: v4l2-ctrls: Add camera location and rotation\n media: v4l2-fwnode: Add helper to parse device properties\n include: v4l2-ctrl: Sort forward declarations\n media: v4l2-ctrls: Sort includes alphabetically\n media: v4l2-ctrls: Add helper to register properties\n media: i2c: ov5670: Parse and register properties\n media: i2c: ov13858: Parse and register properties\n\n .../bindings/media/video-interfaces.txt | 372 +++++++++++++++++-\n .../media/uapi/v4l/ext-ctrls-camera.rst | 153 +++++++\n drivers/media/i2c/ov13858.c | 11 +\n drivers/media/i2c/ov5670.c | 12 +\n drivers/media/v4l2-core/v4l2-ctrls.c | 52 ++-\n drivers/media/v4l2-core/v4l2-fwnode.c | 42 ++\n include/media/v4l2-ctrls.h | 34 +-\n include/media/v4l2-fwnode.h | 47 +++\n include/uapi/linux/v4l2-controls.h | 7 +\n 9 files changed, 718 insertions(+), 12 deletions(-)\n\n--\n2.25.1" }
