Date: Tue, 20 Dec 2022 11:11:32 +0800	[thread overview]
Message-ID: <cec05e22df1b9f33d4681aa4ed2b6b1175a13161.1671071730.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1671071730.git.ming.qian@nxp.com>

Y012 is a luma-only formats with 12-bits per pixel,
expanded to 16bits.
Data in the 12 high bits, zeros in the 4 low bits,
