The Sunchip CX-A99 is a board used in some media players. It features:

An Allwinner A80 ARM SoC (4 * Cortex-A7 + 4 * Cortex-A15 cores) 2 GiB or 4 GiB DDR3 DRAM AXP808 PMIC 16 GB or 32 GB eMMC SDIO Wifi/Bluetooth/FM module SD card slot 1 USB 3.0 connector 2 USB 2.0 connectors SATA connector UART connector (internally) for serial console Ethernet connector (10/100/1000 Mbit/s) HDMI connector Composite video and analog audio connector S/PDIF connector IR remote control receiver

This is a preliminary device tree for use until a device tree is accepted upstream, after which it can be replaced by the upstream version.
