I believe the plan is for Benjamin to land the whole series. Tested on an ACPI device, but an earlier version of the series. Tested on a device that has a Goodix i2c-hid device. Tested on a device that uses normal i2c-hid. It's easier to jam the Goodix support in there. To do this, we totally rejigger the way i2c-hid is organized so that Requirements that necessitate driving a reset GPIO. This touchscreen is special because it has power sequencing The goal of this series is to support the Goodix GT7375P touchscreen.
