Subject: [PATCH v7 02/14] media:Add nt8 and nt10 video format.
Date: Tue, 31 Aug 2021 10:59:03 +0800	[thread overview]
Message-ID: <981eee1270fb47658f7821d59525ff4c53c30644.1630377507.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1630377507.git.ming.qian@nxp.com>

NT8 is 8-bit tiled nv12 format used by amphion decoder.
NT10 is 10-bit tiled format used by amphion decoder.
The tile size is 8x128
