Hi Jiri, Benjamin, As discussed with myself in the linux-input thread about adding icn8505 (ACPI HID CHPN0001) devices to the icn8313 driver: https://www.spinics.net/lists/linux-input/msg51916.html Unfortunately the ACPI node for this non HID compatible device has an ACPI CID (compatility ID) of PNP0C50 causing the i2c-hid driver to bind, which leads to the touchscreen not working (see the second patch commit message for details). Although these 2 patches are not really pretty I believe they are the best way to fix this. Note that even if I do add firmware upload support to the icn8318 driver, we still have the issue left of i2c-hid doing a dev_err(dev, "hid_descr_cmd failed") which is also undesirable. A normal system bootup should have no output for "dmesg --level=err", this is esp. important for the flickerfree boot experience both Fedora and Ubuntu have been working towards. Any _err kernel messages will cause the splash screen to drop back to text-mode breaking the flickerfree experience. So to silence that error we would need to blacklist the CHPN0001 ACPI HID somewhere in the i2c-hid driver anyways.
