Title:
Problem with Goodix i2c touch screen
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have no-name tablet with goodix touch screen which not work in any
version of Ubuntu. Currently I work with 20.04 LTS and kernel
5.15.0-56-lowlatency.
It reports into dmesg:
Goodix-TS i2c-GDIX1002:00: acpi_dev_get_resources returned: 1,
ts->gpio_count: 2, ts->gpio_int_idx: -1
Goodix-TS i2c-GDIX1002:00: i2c test failed attempt 1: -121
Goodix-TS i2c-GDIX1002:00: i2c test failed attempt 2: -121
After reviewing driver's source code I found that such parameters are
very close to code path which is used for bay trail, but my system is
not bay trail. When I comment out check for bay trail driver started
to work:
776c776
< } else if (/*is_byt() &&*/ ts->gpio_count == 2 && ts->gpio_int_idx ==
-1) {
---
> } else if (is_byt() && ts->gpio_count == 2 && ts->gpio_int_idx == -1) {
Maybe this is not correct fix and I may fix something in my system so
it will start to work with 'normal' driver? Or maybe driver need to be
modified as that checking for bay trail is not needed?
Thanks.
