In particular, we set/get formats\nand controls directly on the sensor subdevice instead of proxying through the\nunicam driver node.\n\nNote that these changes rely on https://github.com/raspberrypi/linux/pull/4645\nbeing merged into our kernel tree. That merge will need to be synchronised with\nmerging this change into the libcamera upstream tree else we will have a mismatch\nbetween kernel and userland. In such cases, the pipeline handler will throw an\nerror and fail to start.\n\nThanks,\nNaush\n\nNaushir Patuck (6):\n libcamera: bayer_format: Add conversion helpers to the BayerFormat\n class\n pipeline: raspberrypi: Convert the pipeline handler to use media\n controller\n pipeline: raspberrypi: Return a PixelFormat from findBestMode()\n pipeline: raspberrypi: Remove \"unpacked\" format penalty in mode\n selection\n pipeline: raspberrypi: Account for a missing Unicam embedded data node\n pipeline: raspberrypi: Apply sensor flips at the start of configure()\n\n include/libcamera/internal/bayer_format.h | 4 +\n src/libcamera/bayer_format.cpp | 31 +++\n .../pipeline/raspberrypi/raspberrypi.cpp | 229 +++++++++++-------\n 3 files changed, 170 insertions(+), 94 deletions(-)" }
