+title: Freescale i.MX8qxp Display Controller External Destination Interface
+
+description: |
+  The External Destination unit is the interface between the internal pixel
+  processing pipeline of the Pixel Engine, which is 30-bit RGB plus 8-bit Alpha,
+  and a Display Engine.
+
+  It comprises the following built-in Gamma apply function.

+
+  The output format is 24-bit RGB plus 1-bit Alpha. Conversion from 10 to 8
+  bits is done by LSBit truncation.  Alpha output bit is 1 for input 255, 0
+  otherwise.
