| 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. |
