Subject: [PATCH 1/2] drm/fourcc: add a 10bits fully packed variant of NV12
Date: Mon, 21 May 2018 01:17:04 +0800	[thread overview]
Message-ID: <20180520171705.29690-2-ayaka@soulik.info> (raw)
In-Reply-To: <20180520171705.29690-1-ayaka@soulik.info>

This pixel format is a fully packed and 10bits variant of NV12.
A luma pixel would take 10bits in memory, without any
filled bits between pixels in a stride. The color gamut
follows the BT.2020 standard.
