| 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). |
