Additionally, a single container type will simplify\nthe IPA API.\n\nPatch 1/9 restores the global list of libcamera controls that used to be\nauto-generated. It isn't strictly required by the rest of the series,\nbut has been developed with it, so I've included it.\n\nPatches 2/9 to 4/9 then extend ControlList and ControlId with features\nrequired for V4L2 controls. Patch 5/9 is a drive-by optimisation, and is\nfollowed by patch 6/9 that adds a V4L2ControlId class specialising\nControlId. Patch 7/9 is the bulk of the work, and patch 8/9 is a\nfollow-up cleanup.\n\nPatch 9/9 adds a V4L2 controls validator that has been developed with\nthe series but isn't strictly required either. We can thus leave it out\nfor now if desired until we have a use case.\n\nLaurent Pinchart (9):\n libcamera: control_ids: Generate map of all supported controls\n libcamera: controls: Support getting and setting controls by ControlId\n libcamera: controls: Store control name in ControlId\n libcamera: controls: Make ControlList::find() protected\n libcamera: v4l2_device: Avoid copy of V4L2ControlInfo\n libcamera: v4l2_controls: Add V4L2ControlId\n libcamera: v4l2_device: Replace V4L2ControlList with ControlList\n libcamera: v4l2_controls: Remove V4L2ControlInfo type field\n libcamera: v4l2_controls: Add control validator\n\n include/libcamera/control_ids.h.in | 3 +\n include/libcamera/controls.h | 12 +-\n src/libcamera/camera_sensor.cpp | 4 +-\n src/libcamera/control_ids.cpp.in | 7 +\n src/libcamera/controls.cpp | 62 ++++-\n src/libcamera/gen-controls.py | 7 +-\n src/libcamera/include/camera_sensor.h | 5 +-\n src/libcamera/include/v4l2_controls.h | 55 ++---\n src/libcamera/include/v4l2_device.h | 8 +-\n src/libcamera/pipeline/ipu3/ipu3.cpp | 9 +-\n src/libcamera/pipeline/uvcvideo.cpp | 24 +-\n src/libcamera/pipeline/vimc.cpp | 25 +-\n src/libcamera/v4l2_controls.cpp | 323 ++++++++++++--------------\n src/libcamera/v4l2_device.cpp | 67 +++---\n 14 files changed, 326 insertions(+), 285 deletions(-)"}
