Subject: [PATCH v2 1/3] drm/panel: simple-panel: add the delay timing for Sharp LQ123P1JX31
Date: Fri, 22 Jul 2016 09:42:30 +0800 [thread overview]
Message-ID: <1469151750-7130-1-git-send-email-ykk@rock-chips.com> (raw)
According to page 16 of Sharp LQ123P1JX31 datasheet, we need to add the
missing delay timing. Panel prepare time should be t1 (0.5ms~10ms) plus
t3 (0ms~100ms), and panel enable time should equal to t7 (0ms~50ms), and
panel unprepare time should be t11 (1ms~50ms) plus t12 (500ms~).
