From 86f46565dff313a149b4bd09d4a8655274ef8f33 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 22 Sep 2016 13:35:24 +0300 Subject: [PATCH] dt-bindings: display: display-timing: Add property to configure sync drive edge 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.
