In linux kernel since version 4.5.1 (release Date: 2016-04-12)  
Certain ACPI based tablets with Silead touchscreens do not have
enough data in ACPI tables for the touchscreen driver to handle
the touchscreen properly, as OEMs expected the data to be baked
into the tablet model specific version of the driver shipped
with the OS-image for the device. This option supplies the missing
information. Enable this for x86 tablets with Silead touchscreens.
