[haword]

In default configuration goodix not work.

Please post more info about your problem: goodix_ts dmesg output, what system you use and etc. With just "that doesnt work" no one will be able to help you.

the related dmesg chunck from the original kernel is also needed to know what exact goodix_ts driver your device needs. we don't have them all.

25.772 No input driver specified, ignoring this device.

if i run in terminal - cat /dev/input/event1 and press to screen, in the terminal will be nothing.
if i use kernel 3.0.8+ and drivers from miniand site, in terminal show random data when a press to screen.
if i compile kernel 3.0.8+ from branch lichee-3.0.8-sun4i, in the terminal will be nothing.

Undefine multitouch support here https://github.com/amery/linux-allwinner/blob/allwinner-v3.0-android-v2/drivers/input/touchscreen/goodix_touch.h#L36 or, alternatively, install xserver-xorg-input-multitouch and configure multitouch support accordingly.

[amery]

If that's it, we clearly need a CONFIG_ there

[haword]

if i undefine multitouch, xinput show device in list, but "cat /dev/input/event1" show nothing. in kernel 3.0.8+ from miniand multitouch defined and "cat /dev/input/event1" show random data where press to screen. when i compile kernel not show random data, when press to screen. I do not know, what can i do :(

ask your vendor for the sources so we can diff :-)

@haword above you pasted the related printk in the original kernel, can you show what our goodix_touch says? .. from the A13 SDK we got the goodix_ts 818 driver (see techn@9fd591f) but unfortunatelly there are many more and Goodix has ignored all requests for those drivers yet.

I'm closing this issue as it's a dupe of #26
