Subject: [PATCH v8, 08/17] media: mtk-vcodec: Use pure single core for MT8183
Date:   Fri, 29 Oct 2021 11:55:18 +0800
Message-ID: <20211029035527.454-9-yunfei.dong@mediatek.com>
In-Reply-To: <20211029035527.454-1-yunfei.dong@mediatek.com>
References: <20211029035527.454-1-yunfei.dong@mediatek.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

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