Subject: [PATCH v4, 06/15] media: mtk-vcodec: Use pure single core for MT8183
Date:   Tue, 10 Aug 2021 16:30:38 +0800
Message-ID: <20210810083047.16693-7-yunfei.dong@mediatek.com>
In-Reply-To: <20210810083047.16693-1-yunfei.dong@mediatek.com>
References: <20210810083047.16693-1-yunfei.dong@mediatek.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

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