12description: |
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) 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).
