Description
This is the touchscreen driver for the Official Raspberry Pi 7" Touchscreen. While this device uses a FocalTech FT5406 10 point capactive touchscreen controller it is actually connected to the GPU and not directly accessible to the ARM processor.
In order to make the touchscreen data available the GPU provides a memory based interface that can be read by polling an address returned from a mailbox call.
The Linux driver uses a thread to poll the data approximately 60 times per second so this driver does something similar.
