Subject: [PATCH v4 08/17] soc: mediatek: add mtk-mmsys config API for mt8195 vdosys1
Date: Wed, 25 Aug 2021 18:05:22 +0800	[thread overview]
Message-ID: <20210825100531.5653-9-nancy.lin@mediatek.com> (raw)
In-Reply-To: <20210825100531.5653-1-nancy.lin@mediatek.com>

Add mmsys config API. The config API is used for config mmsys reg.
Some mmsys regs need to be setting according to the HW engine binding
to the mmsys simultaneously.
