Subject: [PATCH 01/26] dt-bindings: display: display-timing: Add property to configure sync drive edge
Date: Thu, 1 Sep 2016 14:22:55 +0300 [thread overview]
Message-ID: <20160901112320.15246-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20160901112320.15246-1-peter.ujfalusi@ti.com>
There are display panels which demands that the sync signal is driven on
different edge than the pixel data.
With the syncclk-active property we can specify the clk edge to be used to
drive the sync signal. When the property is missing it indicates that the
sync is driven on the same edge as the pixel data.
