This is to minimise the \"wobble\"\neffect of the rolling shutter in the sensor. The rkisp1 and ipu3 IPAs are updated\nto use the minimum reported hblank value in their calculations for the same reason.\n\nPatches 1-2 adds a max line length field to the IPACameraSensorInfo and CameraMode structures.\nPatchs 3-6 update the IPA and pipeline handler to pass around a current line length value.\nPatches 7-8 update the calculations to return a hblank number to program in the sensor.\nPatch 9 updates the embedded data parsers to extract current line length values.\n\nRegards,\nNaush\n\nNaushir Patuck (9):\n camera_sensor: Add minimum and maximum line length to\n IPACameraSensorInfo\n ipa: raspberrypi: Add minimum and maximum line length fields to\n CameraMode\n ipa: raspberrypi: Pass lineLength into the CamHelper API\n pipeline: ipa: raspberrypi: Add HBLANK control to DelayedControls\n ipa: raspberrypi: Add pixel clock rate to the CameraMode structure\n ipa: raspberrypi: Add line length to DeviceStatus\n ipa: raspberrypi: Add line length calculations helper functions\n ipa: raspberrypi: Allow full line length control\n ipa: raspberrypi: Extract line length from the embedded data parser\n\n include/libcamera/ipa/core.mojom | 21 +++--\n include/libcamera/ipa/raspberrypi.mojom | 1 +\n src/ipa/ipu3/ipu3.cpp | 2 +-\n src/ipa/raspberrypi/cam_helper.cpp | 81 ++++++++++++++-----\n src/ipa/raspberrypi/cam_helper.h | 18 +++--\n src/ipa/raspberrypi/cam_helper_imx219.cpp | 10 ++-\n src/ipa/raspberrypi/cam_helper_imx290.cpp | 5 +-\n src/ipa/raspberrypi/cam_helper_imx296.cpp | 10 ++-\n src/ipa/raspberrypi/cam_helper_imx477.cpp | 39 +++++----\n src/ipa/raspberrypi/cam_helper_imx519.cpp | 39 +++++----\n src/ipa/raspberrypi/cam_helper_ov5647.cpp | 5 +-\n src/ipa/raspberrypi/cam_helper_ov9281.cpp | 5 +-\n src/ipa/raspberrypi/controller/camera_mode.h | 6 +-\n .../raspberrypi/controller/device_status.cpp | 1 +\n .../raspberrypi/controller/device_status.h | 4 +-\n src/ipa/raspberrypi/raspberrypi.cpp | 61 ++++++++------\n src/ipa/rkisp1/rkisp1.cpp | 2 +-\n src/libcamera/camera_sensor.cpp | 6 +-\n .../pipeline/raspberrypi/raspberrypi.cpp | 1 +\n 19 files changed, 216 insertions(+), 101 deletions(-)" }
