Patch 3/3 is the crux of the change, meant to address\nconstraints faced on Nautilus and Soraka.\n\nThis is a RFC where only preliminary testing have been done.\nExtensive testing and further discussions are still under-way.\n\nUmang Jain (3):\n libcamera: base: camera_sensor: Expose sensor's formats map\n ipu3: cio2: Replicate CameraSensor::getFormats() to a member function\n ipu3: cio2: Customize sensor format selection logic\n\n include/libcamera/internal/camera_sensor.h | 1 +\n src/libcamera/pipeline/ipu3/cio2.cpp | 115 ++++++++++++++++++++-\n src/libcamera/pipeline/ipu3/cio2.h | 5 +\n 3 files changed, 119 insertions(+), 2 deletions(-)"}
