Subject: [PATCH v6, 02/15] media: mtk-vcodec: Using firmware type to separate different firmware architecture
Date:   Sat, 22 Jan 2022 11:53:03 +0800
Message-ID: <20220122035316.18179-3-yunfei.dong@mediatek.com>
In-Reply-To: <20220122035316.18179-1-yunfei.dong@mediatek.com>
References: <20220122035316.18179-1-yunfei.dong@mediatek.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

MT8173 platform use vpu firmware, mt8183/mt8192 will use scp
firmware instead, using chip name is not reasonable to separate
different firmware architecture. Using firmware type is much better.
