Subject: [PATCH v1, 01/14] media: mtk-vcodec: Get numbers of register bases from DT
Date: Wed, 7 Jul 2021 14:21:44 +0800 [thread overview]
Message-ID: <20210707062157.21176-2-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20210707062157.21176-1-yunfei.dong@mediatek.com>
Different platform may has different numbers of register bases. Gets the
numbers of register bases from DT (sizeof(u32) * 4 bytes for each).
