I used nanopi 2 fire from friendlyarm.I want to work with GT911 goodix touch panel. it has 6 pin: 1 for reset(i just connected to one of gpio), 2 for vdd3.3 volt,3 for GND, 4 for irq (i connect it to gpioc11) and SDA and SCL (connect to pin 3 & 5 as I2C-0). I download Linux kernel 4.4.y with this source code to active goodix touch screen:
git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
I active goodix as the module in the kernel, and follow the page to compile kernel , at last copy the files to SD.(run make command,copy zimage and dtb file to boot sd). when I run this code:
root@NanoPi2-Fire:/# find -iname goodix*
./sys/bus/i2c/drivers/Goodix-TS
./sys/firmware/devicetree/base/soc/i2c@c00a6000/goodix_ts@5d
./sys/firmware/devicetree/base/soc/i2c@c00a6000/goodix_ts@5d/goodix,irq-gpio

If you see Godix entries under /sys, the driver should already be loaded (verify withlsmod, assuming you compiled the driver as a module. If you didn't, compile it as a module, much easier to test this way.). Look into the output ofdmesgafter boot (or after you attach the device) to see if there are any godix-related messages (don't grep, context is important). If everything works, the touchpad will likely show up as kernel input devices in/dev/input(useevteston them), but thedmesgoutput will probably give you details on that.

thanks for the reply. at first, can I ask you a question? Is there any config for 'int' and 'reset' gpio pin in the source of a kernel or in the device?where am I set irq and reset pin for GT911? and also I will check that you said. really thanks for help

The proper drive should control the reset pin, and it should also route the IRQ pin properly so it generates an interrupt. First place to look is the source code of the driver and/or at the module parameters. (I haven't done this; I haven't even google dthe source code of the driver, but since you compiled it, you should have it).

The proper drive should control the reset pin, and it should also route the IRQ pin properly so it generates an interrupt. First place to look is the source code of the driver and/or at the module parameters. (I haven't done this; I haven't even google dthe source code of the driver, but since you compiled it, you should have it).

If you see Godix entries under /sys, the driver should already be loaded (verify with
lsmod, assuming you compiled the driver as a module. If you didn't, compile it as a module, much easier to test this way.). Look into the output ofdmesgafter boot (or after you attach the device) to see if there are any godix-related messages (don't grep, context is important). If everything works, the touchpad will likely show up as kernel input devices in/dev/input(useevteston them), but thedmesgoutput will probably give you details on that.– dirkt
