The inet86dz board is a board used in 7" tablets from various oems. These tablets are a23 based 7" tablets featuring a 1024x600 LCD, 512MB RAM, 4G NAND, rtl8188etv usb wifi, gsl1680 touchschreen, micro-sd slot, 3.5mm headphone jack and a micro-usb otg connector which doubles as charging port.
This seems awfully similar to the sun8i-a23-q8-tablet, any reason not to include that or sun8i-q8-common.dtsi?
