Without enabling the\ncapability, the stream arguments to subdev ioctls is ignored (subdev\ninternal routing configuration still works, but all routes then hardcode\nstream 0 on both the sink and source sides).\n\nThis small patch series updates libcamera to enable the stream\ncapbility. It starts by updating the kernel headers in patch 1/2\n(updating to v6.4 would have been enough, but there's no reason not to\nuse the most recent headers), and then enables the client capability in\npatch 2/2.\n\nLaurent Pinchart (2):\n include: linux: Update kernel headers to version v6.7\n libcamera: v4l2_subdevice: Enable streams API when supported\n\n include/libcamera/internal/v4l2_subdevice.h | 2 +-\n include/linux/README | 2 +-\n include/linux/dma-buf.h | 84 ++\n include/linux/drm_fourcc.h | 128 +-\n include/linux/intel-ipu3.h | 7 +-\n include/linux/media-bus-format.h | 13 +-\n include/linux/media.h | 29 +-\n include/linux/v4l2-common.h | 39 -\n include/linux/v4l2-controls.h | 1250 ++++++++++++++++++-\n include/linux/v4l2-mediabus.h | 4 -\n include/linux/v4l2-subdev.h | 56 +-\n include/linux/videodev2.h | 69 +-\n src/libcamera/v4l2_subdevice.cpp | 15 +\n 13 files changed, 1551 insertions(+), 147 deletions(-)\n\n\nbase-commit: 89227a428a82e724548399d35c98ea89566f9045" }
