Subject: [PATCH v4,11/22] media: mediatek: vcodec: initialize msg and vsi information
Date: Mon, 29 Jan 2024 14:30:14 +0800 [thread overview]
Message-ID: <20240129063025.29251-12-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20240129063025.29251-1-yunfei.dong@mediatek.com>
Need to initialize msg and vsi information before sending to optee-os, then
calling optee invoke command to send the information to optee-os.
For the optee communication interface is different with scp, using
flag to separate them.
