As stated above, if supported by SMARC
CN14
up to two MIPI DSI (Display Serial Interface) displays.
The signals for MIPI DSI are carried to same connector CN14 used for LVDS interface. Proper setting of
dual DIP switch SW6 is necessary for its availability.
The power for LCD panel (VDD_LCD0) and panel backlight (VDD_BKLT0) are the same is in LVDS mode.
Also in this case, the selection is made by CN18 and CN19, as described above.
Finally, the DDC Clock and Data Lines used for Flat Panel Detection and Control are the same is in LVDS
mode.
