Subject: [PATCH] memory: mtk-smi: Add ostd setting for mt8192
Date: Fri, 7 Mar 2025 13:45:08 +0800 [thread overview]
Message-ID: <20250307054515.23455-1-xueqi.zhang@mediatek.com> (raw)
Add initial ostd setting for mt8192. All the settings come from DE.
These settings help adjust Multimedia HW's bandwidth limits to achieve
a balanced bandwidth requirement.
Without this, the VENC HW work abnormal while stress testing.
Fixes: 02c02ddce427 ("memory: mtk-smi: Add mt8192 support")
