Hi Bjorn,

Here is the touchscreen driver: https://android.googlesource.com/kernel/msm/+/android-msm-wahoo-4.4-oreo-m2/drivers/input/touchscreen/stm/

Here are the device tree files: https://android.googlesource.com/kernel/msm/+/android-msm-wahoo-4.4-oreo-m2/arch/arm64/boot/dts/lge/

Do note that Timur stated in a later thread this patch is probably not
suitable for stable but I'd be happy for a second opinion!

Cheers,
Nathan
