+description: >
+  This panel requires a dual-channel DSI host to operate and it supports
+  only left-right split mode, where each channel drives the left or right
+  half of the screen and only video mode.
+
+  Each of the DSI channels controls a separate DSI peripheral.
+  The peripheral driven by the first link (DSI-LINK1), left one, is
+  considered the primary peripheral and controls the device.
