13  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), left or even, is considered the primary
19  peripheral and controls the device. The 'link2' property contains a phandle
20  to the peripheral driven by the second link (DSI-LINK2, right or odd).
21
22  Note that in video mode the DSI-LINK1 interface always provides the left/even
23  pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
24  is possible to program either link to drive the left/even or right/odd pixels
25  but for the sake of consistency this binding assumes that the same assignment
26  is chosen as for video mode.
