Subject: [PATCH v2 17/19] media: v4l2: Add 10-, 12- and 16-bpc 4:4:4 packed VUY formats
Date: Tue, 3 Nov 2020 00:41:00 +0200 [thread overview]
Message-ID: <20201102224102.30292-18-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20201102224102.30292-1-laurent.pinchart@ideasonboard.com>
Add three new formats storing packed YUV 4:4:4 in 10-, 12- and 16-bpc
variants, with component order VUY. They are used by the Xilinx Video
Frame Buffer Read/Write IP cores.
