Subject: [PATCH v5 02/14] media:Add nt8 and nt10 video format.
Date: Tue, 27 Jul 2021 11:20:45 +0800	[thread overview]
Message-ID: <ee482c18fdaae121e3c9495d07b0f3eb1661e36e.1627353315.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1627353315.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
