Technically touchscreen chip is FT5406 but all hardware communication is performed by VideCore and only final results are presented to ARM part through memory region shared between VC and ARM. evdev is used as userland interface. FT5406 supports up to 10 touchpoints, but for now driver emulates single touch device because I do not have GUI bits to test this functionality. Driver is not enabled in default config for RPI and RPI2 Tested with: evdev-dump, tslib
