This is a TSP driver for touchscreen chip mms144 of MELFAS. It uses soft I2C interface and supports single touch.
This driver uses polling method. If there are touch events, mms144_interrupt() reads and returns 0. If not, mms144_interrupt() returns -1.
Where exactly will this driver be used inside U-Boot? So far, we don't have any GUI support, do what is a touch driver good for?
Are you just adding dead code here?
Best regards,
Wolfgang Denk
