The hx83112b supports 10 point multitouch with hardware tracking of touch points. It is the touchschreen used by the Fairphone 3. Note that a datasheet was unavailable for this device, so it was built based on the Android driver that was tagged as GPLv2. This series is a complete rewrite, though, and the code bears no resemblence to the original implementation. It is expected that this driver can be made to work on other hx83xxx devices, especially the hx83112a used in the Fairphone 4. However, since we have been unable to verify this, this driver only declares compatibility with the hx83112b and uses very specific file names.
