+description: |
+ This panel requires a dual-channel DSI host to operate. It supports two modes:
+ - left-right: each channel drives the left or right half of the screen
+ - even-odd: each channel drives the even or odd lines of the screen
+
+ Each of the DSI channels controls a separate DSI peripheral. The peripheral
+ driven by the first link (DSI-LINK1) is considered the primary peripheral
+ and controls the device. The 'link2' property contains a phandle to the
+ peripheral driven by the second link (DSI-LINK2).
