Subject: [PATCH v11 2/7] MIPS: Loongson64: dts: introduce ls3A4000 evaluation board
From: suijingfeng <suijingfeng@...ngson.cn>
The board name is LS3A4000_7A1000_EVB_BOARD_V1.4, it consist of 1.8Ghz
mips64r5 4-core CPU and LS7A1000 bridge chip. It has PCIe GEN2 x8 slot,
therefore can play with discrete graphics card.
While the integrated display copntroller is equipped with a VGA output
and a DVI output, the VGA is connect to the DVO0 output port of the
display controller, the DVI is connected to DVO1 output port of the
display controller.
