Dear All, please assist me in porting GSL1680 touchscreen driver to Linux x86/86_64 kernel. As a testing device I have tablet =Chuwi vi8 super. Specs of it http://techtablets.com/chuwi-vi8/ (baytrail based intel z3735f). I have successfully run on it Linux x86 and x86_64 (Arch linux, Ubuntu, Linux mint, sysrescue cd linux distros), the main last problem is - there is NO touch screen driver for Silead GSL1680 which is used in this tablet.
I have successfully porting to x86_64 userspace driver https://github.com/rastersoft/gsl1680. BUT the problem is according http://linux-sunxi.org/GSL1680 to communicate with chip controller of this touchscreen you should 1st initialize it via setting IOCNTL line to 1, this line is mapped to GPIO pin. The main problem - how to determine without any documentation, having only device with Android 4.4 and Windows 8.1 with working touch screen which gpio pin serve IOCNTL. Please help to find out gpio pin for IOCNTL touch screen on Chuwi vi8 (baytrail) platform or with porting kernel level drive to Linux vanilla kernel for x86 plaforms. PS: I tend to run user space mentioned above driver because porting from sunxi linux driver into vanilla for x86 platforms is not so easy way due a lot of differences of included platform headers files.
