Subject: [PATCH v14, 08/19] media: mtk-vcodec: Use pure single core for MT8183
Date: Wed, 15 Dec 2021 14:15:41 +0800	[thread overview]
Message-ID: <20211215061552.8523-9-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20211215061552.8523-1-yunfei.dong@mediatek.com>

Separates different architecture for hardware: pure_sin_core
and lat_sin_core. MT8183 is pure single core. Uses .hw_arch to
distinguish.
