title: JDI LPM102A188A 2560x1800 10.2" DSI Panel

description: |
  This panel requires a dual-channel DSI host to operate. It supports two modes:
  - left-right: each channel drives the left or right half of the screen
  - even-odd: each channel drives the even or odd lines of the screen

  Each of the DSI channels controls a separate DSI peripheral. The peripheral
  driven by the first link (DSI-LINK1) is considered the primary peripheral
  and controls the device. The 'link2' property contains a phandle to the
  peripheral driven by the second link (DSI-LINK2).
