2020-10-04	qcam: Remove unneeded './' file prefix in *.qrc	Laurent Pinchart
	There's no need to prefix files in the local directory with './'. Drop it. While at it, add indentation to make the *.qrc files more readable. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2020-06-09	qcam: Specify Feather icons license in DEP5	Laurent Pinchart
	Specify the license of the Feather icons files in the .reuse/dep5 file. Technically speaking the SVG format supports comments, SPDX could thus be used, but that would be impractical both due to the large number of files, and the fact that they would then diverge from the upstream project. We can remove the README.md file, as it now only contains redundant or incorrect information: the license and project URL are contained in the DEP5 file, and the comment related to generation of the GRC file is outdated as the file is now manually edited to only include the icons that we need.

2020-06-09	libcamera: Add missing SPDX headers to miscellaneous small files	Laurent Pinchart
	Add missing SPDX headers to miscellaneous small files. Use CC0-1.0 for meson.build, .gitignore and the small include/linux/README, and licenses matching the corresponding component for other files.

2020-05-02	qcam: Add RAW capture support	Niklas Söderlund
	Add a toolbar button that captures RAW data to disk. The button is only enabled if the camera is configured to provide a raw stream to the application. Only when the capture action is triggered will a request with a raw buffer be queued to the camera.

2020-03-24	qcam: viewfinder: Display icon when stopping capture	Laurent Pinchart
	When stopping capture, display an icon instead of the last frame. This is required to be able to release the last buffer when the viewfinder operators in zero-copy mode.

2020-02-14	qcam: Provide save image functionality	Kieran Bingham
	Implement a save image button on the toolbar which will take a current viewfinder image and present the user with a QFileDialog to allow them to choose where to save the image. Utilise the QImageWriter to perform the output task. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
