The goal of this series is to support the Goodix GT7375P touchscreen.
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 pretended to have a Goodix i2c-hid device on
it. I don't have a device with GT7375P setup yet and the person who
has been testing remotely for me hasn't tested this exact series. I
think it should still work, though.
- NOT tested on any ACPI devices (just compile tested).
There are probably still small nits, but hopefully we're getting
closer to something people like.
Changes in v4:
- Fully rejigger so ACPI and OF are full subclasses.
- ("arm64: defconfig: Update config names for i2c-hid rejigger") new for v4.
- Totally redid based on the new subclass system.
Changes in v3:
- Rework to use subclassing.
- Removed Benjamin as a maintainer.
- Fixed compatible in example.
- Updated description.
- Rework to use subclassing.
Changes in v2:
- Use a separate compatible string for this new touchscreen.
- Get timings based on the compatible string.
- ("dt-bindings: HID: i2c-hid: Introduce bindings for the Goodix GT7375P") new in v2.
