Subject: [PATCH v2 2/3] drm/panel: boe-tv101wum-nl6: Reduce lcm_reset to send initial code time
Date: Tue, 10 Jan 2023 13:54:52 +0800 [thread overview]
Message-ID: <1673330093-6771-3-git-send-email-xinlei.lee@mediatek.com> (raw)
In-Reply-To: <1673330093-6771-1-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.
Fixes: a869b9db7adf ("drm/panel: support for boe tv101wum-nl6 wuxga dsi video mode panel")
