The rk3318 A95X Z2 boards are sold as TV box. No further documentation is given, but from the dts files extracted it seems that the rk3318 processor is simulair to the rk3328. This dts file contains only the basic nodes that have support in the mainline kernel. Included extra dtsi file for U-boot specific properties.
