The same PD0..PD9 pins are used for either DSI or LVDS. Other than having to use the combo D-PHY, LVDS output is configured in the same way as on older chips. This series enables the sun6i MIPI D-PHY to also work in LVDS mode. It is then configured by the LCD TCON, which allows connecting a single-link LVDS display panel.
