The Chuwi V7 is an A10 (sun4i) based tablet with 1G of RAM, 16G of nand flash,
microsd slot, 7" 1024x768 lvds ips panel, mini hdmi out, headphones out,
stereo speakers, front & back camera and usb wifi.
It is clearly marked "CHUWI", "V7" and "Model: CW0825" on the back of the
tablet.

This is mostly looking good, as usual, but I have a few comments on
it.

I just merged a patch from Chen-Yu that add a DTSI for the AXP209, you
should probably use it to remove some of the boilerplate.

Would you consider switching to the label-based syntax instead of
replicating the whole DT tree like you did for the A31s DTSI?
