Applying flips before setting a format is crucial to obtain an\n up to data Bayer pattern order. In order to simplify setting a Transform\n on the camera sensor, a new \"transform\" member is added to\n V4L2SubdeviceFormat.\n\nNo functional changes intended for the RPi and the IPU3 pipeline handlers.\n\nJacopo Mondi (5):\n libcamera: camera_sensor: Verify flips support\n libcamera: camera_sensor: Validate Transform\n libcamera: camera_sensor: Apply flips at setFormat()\n libcamera: rkisp1: Add support for Transform\n documentation: sensor_drivers: Document H/V flip\n\n Documentation/sensor_driver_requirements.rst | 12 ++\n include/libcamera/internal/camera_sensor.h | 5 +\n include/libcamera/internal/v4l2_subdevice.h | 2 +\n src/libcamera/camera_sensor.cpp | 106 +++++++++++++++++-\n src/libcamera/pipeline/ipu3/cio2.cpp | 6 +-\n src/libcamera/pipeline/ipu3/cio2.h | 4 +-\n src/libcamera/pipeline/ipu3/ipu3.cpp | 73 ++----------\n .../pipeline/raspberrypi/raspberrypi.cpp | 86 +++-----------\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 16 ++-\n src/libcamera/v4l2_subdevice.cpp | 7 ++\n 10 files changed, 172 insertions(+), 145 deletions(-)\n\n--\n2.39.0" }
