It's based on\ntop of a series from Han-Lin [1] and another from Kate Hsuan [2] (both of which\nseries are pretty neat, by the way)\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 and removed both all of that\nfunctionality (including the open()/close() of the VCM subdev) from Kate's\nwork instead.\n\nThanks\nDan\n\n[0] https://patchwork.linuxtv.org/project/linux-media/list/?series=6792\n[1] https://patchwork.libcamera.org/project/libcamera/list/?series=2743\n[2] https://patchwork.libcamera.org/project/libcamera/list/?series=2750\n\nDaniel Scally (5):\n libcamera: Add support for ancillary links to MediaLink\n libcamera: media_device: Handle ancillary links in populateLinks()\n libcamera: ipu3-cio2: Discover VCMs through ancillary links\n ipa: ipu3: Send lens controls to pipeline handler\n ipa: ipu3: af: Remove v4l2 interaction from AF algorithm\n\n include/libcamera/internal/media_object.h | 10 +++++\n include/linux/media.h | 1 +\n src/ipa/ipu3/algorithms/af.cpp | 29 +------------\n src/ipa/ipu3/algorithms/af.h | 3 --\n src/ipa/ipu3/ipu3.cpp | 4 ++\n src/libcamera/media_device.cpp | 52 ++++++++++++++++-------\n src/libcamera/media_object.cpp | 24 ++++++++++-\n src/libcamera/pipeline/ipu3/cio2.cpp | 45 +++++++++++---------\n 8 files changed, 101 insertions(+), 67 deletions(-)"}
