[v4] dt-bindings: input: Goodix GT7986U SPI HID Touchscreen

[PATCH v4 0/2] dt-bindings: input: Goodix GT7986U SPI HID Touchscreen

Posted by Charles Wang 1 week, 5 days ago

The Goodix GT7986U touch controller report touch data according to the
HID protocol through the SPI bus. However, it is incompatible with
Microsoft's HID-over-SPI protocol.

The patchset introduces the following two changes:
1) Add goodix,gt7986u-spifw.yaml.
2) Modify the driver to align with the device binding file.
