Subject: [PATCH v5 3/3] dt-bindings: mips: loongson: introduce board specific dts
From: suijingfeng <suijingfeng@...ngson.cn>
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.
documnet can be found from [1].
Another one is loongson 3A4000 evb board, this board have a vga and dvi
interface.
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.
