	Provide the OV64A40 tuning files for the Arducam Omnivision camera module to operate on the VC4 ISP architecture on Raspberry Pi 4 and below.

2023-12-07	meson: Tag all installed files	Laurent Pinchart
	Meson uses tags to sort installed files in categories, and makes it possible to install a subset of the files using the '--tags' argument to 'meson install'. This is typically used by distributions to split the runtime, development and documentation files into separate packages. By default, meson tries to guess the correct tag for installed files, but can't always do so properly. Mark the install targets that meson can't guess with the correct install_tag. As the feature has been introduced in meson 0.60, bump the minimum meson version. The latest LTS release of all major distributions that libcamera currently targets ship a recent enough meson version.

2023-05-04	pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi code	Naushir Patuck
	Split the Raspberry Pi pipeline handler and IPA source code into common and VC4/BCM2835 specific file structures. For the pipeline handler, the common code files now live in src/libcamera/pipeline/rpi/common/ and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/. For the IPA, the common code files now live in src/ipa/rpi/{cam_helper,controller}/ and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/. To build the pipeline and IPA, the meson configuration options have now changed from "raspberrypi" to "rpi/vc4": meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4 Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
