Goodix i2c-hid touchscreens are mostly i2c-hid compliant but have some special power sequencing requirements, including the need to drive a reset line during the sequencing. Let's use the new rejiggering of i2c-hid to support this with a thin wrapper driver to support the first Goodix i2c-hid touchscreen: GT7375P Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
