+description:
+
+  The DCSS (display controller sub system) is used to source up to three
+  display buffers, compose them, and drive a display using HDMI 2.0a(with HDCP
+  2.2) or MIPI-DSI. The DCSS is intended to support up to 4kp60 displays. HDR10
+  image processing capabilities are included to provide a solution capable of
+  driving next generation high dynamic range displays.
