Subject: media: nxp: imx8-isi: Mark all crossbar sink pads as MUST_CONNECT Author: Laurent Pinchart laurent.pinchart@ideasonboard.com Date: Mon Jan 15 04:16:29 2024 +0200
All the sink pads of the crossbar switch require an active link if they're part of the pipeline. Mark them with the MEDIA_PAD_FL_MUST_CONNECT flag to fail pipeline validation if they're not connected. This allows removing a manual check when translating streams.
