This panel requires a dual-channel DSI host to operate. It supports two modes:
14
+
- left-right: each channel drives the left or right half of the screen
15
+
- even-odd: each channel drives the even or odd lines of the screen
16
+
17
+
Each of the DSI channels controls a separate DSI peripheral. The peripheral
18
+
driven by the first link (DSI-LINK1) is considered the primary peripheral
19
+
and controls the device. The 'link2' property contains a phandle to the
20
+
peripheral driven by the second link (DSI-LINK2).
