arm64: dts: rockchip: rk3328: Add Orange Pi R1 Plus
Browse files Browse the repository at this point in the history 
Orange Pi R1 Plus is a Rockchip RK3328 based SBC by Xunlong.

This device is similar to the NanoPi R2S, and has a 16MB
SPI NOR (mx25l12805d). The reset button is changed to
directly reset the power supply, another detail is that
both network ports have independent MAC addresses.
