As there are no publicly available data sheets for these devices, the implementation is based on the driver of the downstream Android kernel used in the Fairphone 3. This patch is a complete rewrite, though, and the code bears no resemblence to the original implementation. The driver has been tested on the aforementioned phone.

This driver supports only the I2C bus but it uses regmap so SPI support could be added later. The touchscreen can retrieve some defined zone that are handled as buttons (according to the hardware). That is why it handles button and multitouch events.

Input: goodix - add support for controllers without flash 2021-09-21T05:00:29+00:00 Hans de Goede hdegoede@redhat.com 2021-09-21T04:08:53+00:00 09182ed20c04d1b3a3a0d232d7748e745a438acd Some Goodix touchscreen controllers, such as for example the GT912, don't have flash-storage for their firmware. These models require the OS to load the firmware at runtime, as well as some other special handling. Add support for this to the goodix driver. This patch was developed and tested on a Glavey TM800A550L tablet. Note the "goodix,main-clk" and "firmware-name" device-properties used by the new code are *not* documented in the Documentation/devicetree/bindings/input/touchscreen/goodix.yaml device-tree bindings for now. Not documenting these is intentional. This is done because this code has only been tested on x86/ACPI so far, where devicetree is not used. Instead these properties are set through a software-fwnode attached to the device by the drivers/platform/x86/touchscreen_dmi.c code. This means that the use of this properties for now is purely a kernel-internal thing and the name/working of the properties may still be changed for now.
