Subject: [PATCH 2/2] drm/panel: boe-tv101wum-nl6: Reduce lcm_reset to send initial code time
Date: Fri, 6 Jan 2023 11:05:21 +0800	[thread overview]
Message-ID: <1672974321-18947-3-git-send-email-xinlei.lee@mediatek.com> (raw)
In-Reply-To: <1672974321-18947-1-git-send-email-xinlei.lee@mediatek.com>

From: Xinlei Lee <xinlei.lee@mediatek.com>

Since the panel spec stipulates that the time from lcm_reset to DSI to
send the initial code should be greater than 6ms and less than 40ms,
so reduce the delay before sending the initial code and avoid panel
exceptions.
