[PATCH 6/7] Input: cyttsp - Set abs params for ABS_MT_TOUCH_MAJOR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The driver is certainly reporting pressure in
cyttsp_report_tchdata() with
input_report_abs(input, ABS_MT_TOUCH_MAJOR, tch->z);
so we should also advertise this capability.
