Now that Han-Lin's series is merged this is based on top\nof master, plus Kate's v3 [1]\n\nThe general principle of the new links is an entity to entity link which will\nbe connected by the kernel between a sensor's entity and an entity for a VCM\ndevice, where those entities have a fwnode match based on the \"lens-focus\"\nproperty against the sensor. These links are then discovered by libcamera and\nfollowed to create an instance of the CameraLens class.\n\nWith the CameraLens available to carry out the controlling of the VCM, I have\npushed the controls to the pipeline handler.\n\nSeries changes in v3: \n\n\t- New patch #2 which splits out from #3\n\t- New patch #7, which renames the existing ctrls_ field to sensorCtrls_\n\tto make clear the distinction.\n\nThanks\nDan\n\n[1] https://patchwork.libcamera.org/patch/15011/\n\n\nDaniel Scally (9):\n libcamera: Add members to MediaEntity to support ancillary entities\n include: linux: Add MEDIA_LNK_FL_ANCILLARY_LINK\n libcamera: media_device: Handle ancillary links in populateLinks()\n libcamera: camera_sensor: Discover VCMs through ancillary links\n libcamera: camera_lens: Add function to fetch subdev controls\n libcamera: ipa: Add lens control member to ipu3 ipa interface\n libcamera: ipa: Rename ctrls_ member\n libcamera: ipu3: Pass lens controls to config info\n ipa: ipu3: Send lens controls to pipeline handler\n\n include/libcamera/internal/camera_lens.h | 4 ++\n include/libcamera/internal/camera_sensor.h | 1 +\n include/libcamera/internal/media_object.h | 4 ++\n include/libcamera/ipa/ipu3.mojom | 1 +\n include/linux/media.h | 1 +\n src/ipa/ipu3/ipu3.cpp | 32 ++++++++-----\n src/libcamera/camera_lens.cpp | 11 +++++\n src/libcamera/camera_sensor.cpp | 39 +++++++++++++++\n src/libcamera/media_device.cpp | 55 +++++++++++++++-------\n src/libcamera/media_object.cpp | 15 ++++++\n src/libcamera/pipeline/ipu3/ipu3.cpp | 5 ++\n 11 files changed, 141 insertions(+), 27 deletions(-)" }
