This patch introduce two dts, one for lemote a1901(aka LX-6901) motherboard which one only one vga output connected to DVO1. more document can be found from [1]. Another one is ls3A4000+ls7a1000 evb board, this board have a VGA and DVO interface. The VGA is connected to the DVO0 and the dvi is connected to DVO1. We need introduce board specific dts because of we need the device tree to tell how does the connectors and encoders are connected to the DVO port of the display controller.
