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.
