2024-05-13Input: drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König1-1/+1
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

2024-01-30Input: goodix-berlin - add I2C support for Goodix Berlin Touchscreen ICNeil Armstrong1-0/+75
Add initial support for the new Goodix "Berlin" touchscreen ICs over the I2C interface. This initial driver is derived from the Goodix goodix_ts_berlin available at [1] and [2] and only supports the GT9916 IC present on the Qualcomm SM8550 MTP & QRD touch panel. The current implementation only supports BerlinD, aka GT9916.
