12 description: |
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).
