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 Priit Laes (2): ARM: dts: sun4i: gemei-g9: Add touchscreen (Goodix gt801x2) support input: gt801_2plus1 - Add initial support for Goodix GT801 2+1 .../bindings/input/touchscreen/gt801_2plus1.txt | 23 ++ MAINTAINERS | 6 + arch/arm/boot/dts/sun4i-a10-gemei-g9.dts | 26 +- drivers/input/touchscreen/Kconfig | 19 +- drivers/input/touchscreen/Makefile | 1 + drivers/input/touchscreen/gt801_2plus1.c | 375 +++++++++++++++++++++ 6 files changed, 445 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/input/touchscreen/gt801_2plus1.txt create mode 100644 drivers/input/touchscreen/gt801_2plus1.c -- 2.6.3
