+title: Device-Tree for Xilinx Video Timing Controller(VTC)
+
+description:
+  Xilinx VTC is a general purpose video timing generator and detector.
+  The input side of this core automatically detects horizontal and
+  vertical synchronization, pulses, polarity, blanking timing and active pixels.
+  While on the output, it generates the horizontal and vertical blanking and
+  synchronization pulses used with a standard video system including support
+  for programmable pulse polarity.
+
+  The core is commonly used with Video in to AXI4-Stream core to detect the
+  format and timing of incoming video data or with AXI4-Stream to Video out core
+  to generate outgoing video timing for downstream sinks like a video monitor.
