Public bug reported:
I discovered that this model's touchscreen uses a Silead touchscreen
which requires device specific quirks to calibrate the touchscreen so
touch input will work correctly. I have prepared a patch to resolve the
issue and have already confirmed that it does indeed allow the
touchscreen to function correctly. I would appreciate it if this patch
could be included in a future kernel build.
Regarding the patch I have 2 versions of it because upstream changed the
location of the relevant quirks table in 4.19 and newer kernels. You
will want to use the 4.18- patch for older kernels and 4.19+ patch for
newer kernels. They should apply just fine but they may have fuzzing
because the tables have been modified between kernel releases.
Thank you.
