This adds a device tree for the NanoPC-T4 SBC, which is based on the Rockchip RK3399 SoC and marketed by FriendlyELEC. Known working: - Serial - Ethernet - HDMI - USB 2.0 All of the interesting stuff is in a .dtsi because there are at least two other boards that share most of it: NanoPi M4 and NanoPi NEO4.
