Now that\nHan-Lin's series is merged this is based on top of 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, replacing the matching\non driver/device names in Han-Lin's original series.\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 v2: \n\n\t- New patches #4, #5 and #6 adding some extra framework to the IPAIPU3\n\tand pipeline so that I can pass the lensControls as a ControlList in #7\n\t(which was previously #5).\n\t- Dropped the patch amending Kate's work, as Kate squashed it (thanks!)\n\nThanks\nDan\n\n[1] https://patchwork.libcamera.org/patch/15011/\n\nDaniel Scally (7):\n libcamera: Add members to MediaEntity to support ancillary entities\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: 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 | 10 +++++\n src/libcamera/camera_lens.cpp | 11 ++++++\n src/libcamera/camera_sensor.cpp | 42 ++++++++++++++++++++\n src/libcamera/media_device.cpp | 46 +++++++++++++++-------\n src/libcamera/media_object.cpp | 16 ++++++++\n src/libcamera/pipeline/ipu3/ipu3.cpp | 5 +++\n 11 files changed, 126 insertions(+), 15 deletions(-)" }
