A33-OLinuXino is A33 development board designed by Olimex LTD. It has AXP223 PMU, 1GB DRAM, a micro SD card, one USB-OTG connector, headphone and mic jacks, connector for LiPo battery and optional 4GB NAND Flash. It has two 40-pin headers. One for LCD panel, and one for additional modules. Also there is CSI/DSI connector. The dts files are identical to the ones submitted to the upstream kernel.
