This replaces the existing lineLength field.\n\nUpdate the ipu3, raspberrypi and rkisp1 IPAs to use IPACameraSensorInfo::minLineLength\ninstead of IPACameraSensorInfo::lineLength, as logically we will always want to\nuse the fastest sensor readout by default.\n\nSince the IPAs now use minLineLength for their calculations, set the starting\nvalue of the V4L2_CID_HBLANK control to its minimum in CameraSensor::init().\n\nSigned-off-by: Naushir Patuck <naush@raspberrypi.com>\nTested-by: Dave Stevenson <dave.stevenson@raspberrypi.com>\n---\n include/libcamera/ipa/core.mojom | 21
