Subject: [PATCH v2 2/2] drm/mediatek: dsi: fine tune the line time cause by EOTp
Date: Mon, 1 Feb 2021 11:36:03 +0800 [thread overview]
Message-ID: <20210201033603.12616-3-jitao.shi@mediatek.com> (raw)
In-Reply-To: <20210201033603.12616-1-jitao.shi@mediatek.com>
Enabling EoTp will make the line time larger, so the hfp and
hbp should be reduced to keep line time.
