* touchpad_gt7288: Basic driver for Goodix GT7288Harry Cutts2019-09-181-0/+76
A simple driver which allows touch reports and firmware version information to be read. If the appropriate config flag is set, console commands are included for testing. Unlike the other two touchpad drivers already implemented, which simply receive I2C HID events and send them straight out again over USB HID, we want to do some processing on the touchpad data in the board directory. For that reason, this driver leaves handling the touch interrupts up to the user. BRANCH=none BUG=none TEST=With https://crrev.com/c/1716928 patched, run the various host commands and check the output.
