Subject: [RFC PATCH 18/20] lib: image-formats: Add v4l2 formats support
Date: Tue, 19 Mar 2019 22:57:23 +0100 [thread overview]
Message-ID: <c97024b97d3261dcf41aad3c8bc1c5d9906f33c9.1553032382.git-series.maxime.ripard@bootlin.com> (raw)
In-Reply-To: <cover.92acdec88ee4c280cb74e08ea22f0075e5fa055c.1553032382.git-series.maxime.ripard@bootlin.com>
V4L2 uses different fourcc's than DRM, and has a different set of formats.
For now, let's add the v4l2 fourcc's for the already existing formats.
