The Allwinner H616 (and its H618, H700 and T507 package variants with the same die) have 28 video output pins for RGB/SPI and LVDS display. These are in GPIO Bank D and are multiplexed. In RGB mode, pins PD0-PD23 are for 24-bit RGB pixel output, pins PD24-PD27 are for clock, DE, HSYNC and VSYNC. In LVDS mode, pins PD0-PD9 are for LVDS0 and pins PD10-19 for LVDS1, and can be configured by the H616 display engine for either one high- resolution (dual link) or two low resolution displays. Add device tree nodes for the LCD and LVDS pins.
