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.

You gave subject prefix "dt-bindings" but I do not see any bindings
here. Maybe you meant "MIPS: dts:" ?

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 should not be the same as compatible but a user-parseable string.
