[PATCH 0/2] input: Driver for Goodix GT801 2+1 touchscreen

This series adds support for Goodix GT801 2+1 touchscreen controller
and hooks it up on Gemei G9 tablet.

Now about GT801 2+1 - I initially tried to implement this inside the
existing Goodix driver, but unfortunately there are too many small
bits and pieces that would make the otherwise simple driver a
complicated mess:
- endianness differences of coordinate readouts
- totally different touch protocol
- configuration layout and version information
- I2C register differences (2 bytes vs single byte)

To apply the patchset, you need both linux-input/next and
linux-sunxi/next merged.

Patch 1 (Gemei G9 devicetree bits) should go via linux-sunxi tree.
Patch 2 (GT801 2+1 driver implementation) via linux-input
