Just consult your DSDT. It should have all the information you need to get the touchscreen controller working. The exact GPIO pin location might be different for every device, so it's a good idea to check for yourself in any case. If you prefer to use the userspace Silead driver by ???, you may need to do a bit of math to get the correct pin number. Kernel drivers can rely on the kernel to do the work. Consult https://github.com/onitake/gslx680-acpi/blob/master/acpi/gsl-dsdt.aml for the part you need to look for. To obtain your (decompiled) DSDT, use: cp /sys/firmware/acpi/tables/DSDT . iasl -d DSDT -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
