Subject: [PATCH v1 4/6] soc: mediatek: mmsys: add config api for RSZ switching and DCM
Date: Tue, 4 Oct 2022 17:33:17 +0800	[thread overview]
Message-ID: <20221004093319.5069-5-moudy.ho@mediatek.com> (raw)
In-Reply-To: <20221004093319.5069-1-moudy.ho@mediatek.com>

From: "Roy-CW.Yeh" <roy-cw.yeh@mediatek.com>

Due to MT8195 HW design, some RSZs have additional settings that
need to be configured in MMSYS.
