Hello everyone, I've split these patches off the metadata set [1], it'll still take more time to merge the internal pad support as it is evident we need to properly define the recommended sensor APIs to merge the drivers that are using them. In the meantime, these patches are seen as what can be merged for 6.10. The patches include changes to the routing API before the internal pads. [1] <URL:https://lore.kernel.org/linux-media/20240420100518.GA5618@xxxxxxxxxxxxxxxxxxxxxxxxxx/T/#t> changes since v1: - Improve len_routes field documentation in struct v4l2_subdev_routing. changes since v9 metadata set: - Fix metadata format documentation. - Improve language of struct v4l2_subdev_format field documentation when it comes to metadata. - Improved documentation for routing API. - Set (and unset) the V4L2_FMT_FLAG_META_LINE_BASED flag in the framework based on the format, don't rely on the driver to do it. Added a comment to the format list to remind developers to update v4l_fill_fmtdesc when adding new metadata formats. - Drop the patch that moved G_ROUTING below S_ROUTING handling in v4l2-subdev.c. It's no longer needed.
