+description:
+  This is a 6.77" AMOLED video mode display panel on a MIPI-DSI 4-lane
+  interface.
+
+  The panel also requires ELVDD/ELVSS/ELAVDD rails but these are
+  internally managed by the panel via EL_ON1 (ELAVDD) and EL_ON2
+  (ELVDD/ELVSS) control signals, they are not managed by the platform.
+
+  The driver IC for this panel assembly is an RM69220.
