The Remix Mini PC is a "mini computer" using the Allwinner H64 SoC, which appears to be just a relabelled A64. It was launched in 2015 by the now defunct company Jide, and shipped with a desktop optimised version of Android. It features - Allwinner H64 Soc (4 * Arm Cortex-A53 cores) - 1 or 2 GB DRAM - 8 or 16 GB eMMC flash - 100 MBit Ethernet port (using an X-Powers AC200 PHY) - RTL8723BS WiFi & Bluetooth chip - HDMI port - two USB 2.0 ports - 3.5mm AV port - microSD card slot The devicetree covers most peripherals, though there is no agreed binding for the PHY chip yet, so this is left out.
