Subject: [PATCH v5 09/14] media: cadence: csi2rx: Add link validation
Date: Fri, 24 Dec 2021 00:46:10 +0530	[thread overview]
Message-ID: <20211223191615.17803-10-p.yadav@ti.com> (raw)
In-Reply-To: <20211223191615.17803-1-p.yadav@ti.com>

Add media link validation to make sure incorrectly configured pipelines
are caught. Since there is no support for transcoding, rely on the
default link validation function to make sure formats across source and
sink pads are the same.
