Subject: [PATCH v15 14/22] drm/mediatek: add display merge async reset control
Date: Fri, 11 Mar 2022 09:54:58 +0800 [thread overview]
Message-ID: <20220311015506.11232-15-nancy.lin@mediatek.com> (raw)
In-Reply-To: <20220311015506.11232-1-nancy.lin@mediatek.com>
Add merge async reset control in mtk_merge_stop. Async hw doesn't do self
reset on each sof signal(start of frame), so need to reset the async to
clear the hw status for the next merge start.
