Subject: [PATCH v1, 09/14] media: mtk-vcodec: Add new interface to lock different hardware
Date: Wed, 7 Jul 2021 14:21:52 +0800 [thread overview]
Message-ID: <20210707062157.21176-10-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20210707062157.21176-1-yunfei.dong@mediatek.com>
For add new hardware, not only need to lock lat hardware, also
need to lock core hardware in case of different instance start
to decoder at the same time.
