2019-04-19libcamera: Include header related to source file firstLaurent Pinchart
Include the header file corresponding to the source file in the very first position. This complies with the Google C++ coding style guideliens, and helps ensuring that the headers are self-contained. Three bugs are already caught by this change (missing includes or forward declarations) in device_enumerator.h, event_dispatcher_poll.h and pipeline_handler.h. Fix them.

2019-04-19libcamera: Document documentation style and update the code accordinglyLaurent Pinchart
The documentation style for the Doxygen comment blocks is inconsistent in the library. Document the expectations and update all existing comment blocks to match. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Acked-by: Jacopo Mondi <jacopo@jmondi.org>
2019-02-27libcamera: align the documentation for numeric error codesNiklas Söderlund
Rapid growth of the library have resulted in slightly different wording to document that a function returns 0 on success or a negative error code otherwise. Align all different variations.

2019-01-25libcamera: MediaEntity: expose the entity flagsNiklas Söderlund
The media entity flags can be useful for pipeline handlers to find the default device in a media graph which is marked with the MEDIA_ENT_FL_DEFAULT flag. This will be especially useful for the UVC pipeline handler where the entity names differ per device.

Do not use the abreviated version for members, variables and getter methods. Library-wise rename, no intended functional changes.

2019-01-21libcamera: media_object: Set devnode in MediaEntityJacopo Mondi
The MediaEntity::setDeviceNode() function was designed to set the device node path associated with a MediaEntity. The function was there, but the devnode_ member field was never actually set. Fix this. While at there add a getter method for the devnode_ member as it will soon be used.

2019-01-21libcamera: media_object: Add functions to entitiesJacopo Mondi
Media entities convey information about their main function in the 'function' field of 'struct media_v2_entity'. Store the main function in the MediaEntity function_ class member and provide a getter function for that. While at there update comments, keep the MediaPad description in sync with the MediaEntity one and remove a stale TODO entry.

2019-01-09libcamera: Add link handling functionsJacopo Mondi
Add a function to the MediaLink class to set the state of a link to enabled or disabled. The function makes use of an internal MediaDevice method, which is defined private and only accessible by the MediaLink setEnabled() function itself. Also add to MediaDevice a function to reset all links registered in the media graph. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2019-01-08libcamera: Add pointer to MediaDevice to MediaObjectJacopo Mondi
Add a MediaDevice member field to the MediaObject class hierarcy. Each media object now has a reference to the media device it belongs to, and which it has been created by.

2019-01-08libcamera: media_object: Rename major/minor functionsKieran Bingham
The system libraries define macro's for major/minor through <sys/types.h> on some versions of GCC/GLibc. To prevent namespace collisions with these macros, rename our major and minor device node accessors.

2019-01-02libcamera: media_device: Create entities with major and minor numbersJacopo Mondi
Extend the MediaEntity object with device node major and minor numbers, and retrieve them from the media graph using interfaces. They will be used by the DeviceEnumerator to retrieve the devnode path. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-12-31libcamera: Add MediaObject class hierarchyJacopo Mondi
Add a class hierarcy to represent all media objects a media graph represents. Add a base MediaObject class, which retains the global unique object id, and define the derived MediaEntity, MediaLink and MediaPad classes. This hierarchy will be used by the MediaDevice objects which represents and handles the media graph.
