Subject: [PATCH v5, 10/15] media: mtk-vcodec: Add new interface to lock different hardware
Date: Wed, 11 Aug 2021 10:57:56 +0800 [thread overview]
Message-ID: <20210811025801.21597-11-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20210811025801.21597-1-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.
