This adds support for the Ainol AW1, an A20-based 7" tablet from
Ainol.
This version didn't use the dedicated binding for the panel and will
be
fixed in v2 and onwards.
...
The following board-specific features are supported:

LCD panel
Backlight
USB OTG
Buttons
Touchscreen (doesn't work without non-free firmware)
Accelerometer
Battery

The following are untested:

Audio output
Audio speakers
USB via SPCI connector

The following are not supported:

Wi-Fi
Bluetooth
NAND
Audio via SPCI connector

The camera is also not supported at this point.
...
