2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2023-01-10Input: imagis - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron1-4/+4
SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

2022-03-21Input: add Imagis touchscreen driverMarkuss Broks1-0/+367
Add support for the IST3038C touchscreen IC from Imagis, based on downstream driver. The driver supports multi-touch (10 touch points) The IST3038C IC supports touch keys, but the support isn't added because the touch screen used for testing doesn't utilize touch keys. Looking at the downstream driver, it is possible to add support for other Imagis ICs of IST30**C series.
