+title: Goodix GT7986U SPI HID Touchscreen
+
+maintainers:
+ - Charles Wang <charles.goodix@gmail.com>
+
+description: |
+ Supports the Goodix GT7986U touchscreen.
+ This touch controller reports data packaged according to the HID protocol
+ over the SPI bus, but it is incompatible with Microsoft's HID-over-SPI protocol.
+
+ NOTE: these bindings are distinct from the bindings used with the
+ GT7986U when the chip is running I2C firmware. This is because there's
+ not a single device that talks over both I2C and SPI but rather
+ distinct touchscreens that happen to be built with the same ASIC but
+ that are distinct products running distinct firmware.
