From: Chris Morgan <macromor...@hotmail.com>
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 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, LVDS0, and LVDS1 pins.
