This functionality is unimplemented\ncurrently.\n\nThis series adds a new type of CameraSensor class, which can be used to\nrepresent cameras that do not support controls made mandatory by\nCameraSensorLegacy. Lots of this implementation is untested, such as\nFocusLens.\n\nThis series is tested and works on the Debix Model A iMX8 MPlus with a\nGC2145 camera sensor outputting UYVY8_1X16, on top of origin/master,\nalongside with these kernel patches:\n\nhttps://lore.kernel.org/linux-media/20251209123136.273938-1-isaac.scott@ideasonboard.com/T/#t\n\nI am marking this series as RFC because I am keen to know if any other\ndevelopers have any ideas on how to improve the series, or if there are\nother considerations / edge cases that I need to address.\n\nBest wishes,\nIsaac\n\nIsaac Scott (6):\n camera_sensor: Add camera_sensor_basic\n ipa: rkisp1: Let all controls be optional\n pipeline: rkisp1: Add support for YUV passthrough\n pipeline: rkisp1: Add YUV bypass formats to list of 'raw' formats\n rkisp1_path: Determine if the ISP is bypassed for YUV and RAW formats\n rkisp1: Add bypass configurations to ipa_context\n\n src/ipa/rkisp1/ipa_context.h | 2 +\n src/ipa/rkisp1/rkisp1.cpp | 45 +-\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 75 +-\n src/libcamera/pipeline/rkisp1/rkisp1_path.cpp | 65 +-\n src/libcamera/sensor/camera_sensor_basic.cpp | 965 ++++++++++++++++++\n src/libcamera/sensor/meson.build | 1 +\n 6 files changed, 1098 insertions(+), 55 deletions(-)\n create mode 100644 src/libcamera/sensor/camera_sensor_basic.cpp"}
