Subject: [PATCH v2 21/23] drm/omap: panel-tpo-td028ttec1: Add note for incorrect sync drive edge
Date: Thu, 22 Sep 2016 14:07:06 +0300 [thread overview]
Message-ID: <20160922110708.31242-22-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20160922110708.31242-1-peter.ujfalusi@ti.com>
According to the datasheet of the panel, both data, DEN and sync signals
are expected to be driven on the falling edge of the DOTCLK.
