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. - Tested on an ACPI device, but an earlier version of the series. I believe the plan is for Benjamin to land the whole series. Will said this about the arm64 defconfig change (and provided his Ack): > ...there are a few things I really care about > in defconfig (e.g. things like page size!), generally speaking we don't > need to Ack everything that changes in there. > > That said, might be worth checking whether arm-soc have any defconfig > changes queued in -next so you don't end up with conflicts. Changes in v9: - 120 ms delay => 180 ms delay - Local variable in ACPI code "ihid_of" => "ihid_acpi". - Squash Benjamin's change for ACPI power on. Changes in v8: - Mark suspend/resume as static as per patches robot. Changes in v7: - Rebase atop commit afdd34c5fa40 ("HID: i2c-hid: show the error ...") Changes in v6: - ACPI probe function should have been "static" - Don't export suspend/resume, just export dev_pm_ops from core. - Fixed crash in ACPI module (missing init of "client") - No need for regulator include in the core. - Removed i2c_device_id table from ACPI module. - Suspend/resume are no longer exported from the core. 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.
