Subject: [PATCH v1] memory: mtk-smi: Add ostd setting for mt8186
Date: Wed, 21 May 2025 17:16:16 +0800 [thread overview]
Message-ID: <20250521091626.4283-1-friday.yang@mediatek.com> (raw)
Add initial ostd setting for mt8186. 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 works
abnormal while stress testing.
Fixes: 86a010bfc739 ("memory: mtk-smi: mt8186: Add smi support")
