This touchscreen is special because it has power sequencing requirements that necessitate driving a reset GPIO. To do this, we totally rejigger the way i2c-hid is organized so that it's easier to jam the Goodix support in there. This series was: - Tested on a device that uses normal i2c-hid. - Tested on a device that has a Goodix i2c-hid device. - NOT tested on any ACPI devices (just compile tested). Changes in v5: - Add shutdown_tail op and use it in ACPI. - Added mention of i2c-hid in the yaml itself as per Rob. - Adjusted subject as per Rob. - i2chid_subclass_data => i2chid_ops. - power_up_device => power_up (same with power_down). - subclass => ops. Changes in v4: - ("arm64: defconfig: Update config names for i2c-hid rejigger") new for v4. - Fully rejigger so ACPI and OF are full subclasses. - Totally redid based on the new subclass system. Changes in v3: - Fixed compatible in example. - Removed Benjamin as a maintainer. - Rework to use subclassing. - Updated description. Changes in v2: - ("dt-bindings: HID: i2c-hid: Introduce bindings for the Goodix GT7375P") new in v2. - Get timings based on the compatible string. - Use a separate compatible string for this new touchscreen.
