0013 This panel requires a dual-channel DSI host to operate. It supports two modes:
0014 - left-right: each channel drives the left or right half of the screen
0015 - even-odd: each channel drives the even or odd lines of the screen
0016
0017 Each of the DSI channels controls a separate DSI peripheral. The peripheral
0018 driven by the first link (DSI-LINK1), left or even, is considered the primary
0019 peripheral and controls the device. The 'link2' property contains a phandle
0020 to the peripheral driven by the second link (DSI-LINK2, right or odd).
0021
0022 Note that in video mode the DSI-LINK1 interface always provides the left/even
0023 pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
0024 is possible to program either link to drive the left/even or right/odd pixels
0025 but for the sake of consistency this binding assumes that the same assignment
0026 is chosen as for video mode.
