Perhaps mention hid over i2c here given that's only captured in the commit message. With those nits addressed.

This adds new bindings for the Goodix GT7375P touchscreen. While this touchscreen's communications are based on the generic "i2c-over-hid" protocol, it needs special power sequencing and thus gets its own compatible and bindings. Signed-off-by: Douglas Anderson <dianders@chromium.org> --- (no changes since v3) Changes in v3: - Removed Benjamin as a maintainer. - Fixed compatible in example. - Updated description. Changes in v2: - ("dt-bindings: HID: i2c-hid: Introduce bindings for the Goodix GT7375P") new in v2. .../bindings/input/goodix,gt7375p.yaml | 63 +++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/goodix,gt7375p.yaml
