Subject: media: atomisp: Propagate v4l2_mbus_framefmt.field to CSI port sink pad
Author: Hans de Goede <hdego...@redhat.com>
Date: Fri Apr 12 15:27:53 2024 +0100
Most sensor drivers report V4L2_FIELD_NONE as v4l2_mbus_framefmt.field
value. Propagate this to the v4l2_mbus_framefmt for the CSI port to pass
the link validation done by media_pipeline_start().
Keep the v4l2_mbus_framefmt.field for the source pad of the CSI port
as V4L2_FIELD_ANY to match the ISP sink pad.
