Need Help to add the Touchpad for i2c_designware (Huawei)

[daswars]

Hi, Currently the touchpad on my HUAWEI MateBook X Pro does not work. https://linux-hardware.org/index.php?id=ps/2:cd48-cd48-syna1d31-00-06cb-touchpad

I see that the correct kernel functions are loaded in kconfigs/.config

CONFIG_I2C_DESIGNWARE_CORE=y CONFIG_I2C_DESIGNWARE_PLATFORM=y

The touchpad works with a current Ubuntu. Here the libinput driver is used. As far as I understand it.

Hi, As it looks, the touchpad is not yet supported in the kernel. https://forum.manjaro.org/t/touchpad-syna3602-0911-5288-not-working-at-all/36269/48 Is there an easy way to update to a 4.19.
