You gave subject prefix "dt-bindings" but I do not see any bindings here. Maybe you meant "MIPS: dts:" ?
For board specific devices which is outside of the cpu and bridge chip. 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.
All this is unparseable. Could you use some more advanced grammar check? If you can access Google GMail, it provides a really good grammar helper.

You need to document the new compatible in the bindings.
model = "lemode,a1901";
Model should not be the same as compatible but a user-parseable string.

Is there such a dt property?
