From 4e584ac737884ef0fd80f6836b917972fad86b17 Mon Sep 17 00:00:00 2001 From: Angela Czubak Date: Mon, 18 Aug 2025 23:08:50 +0000 Subject: Input: MT - add INPUT_MT_TOTAL_FORCE flags Add a flag to generate ABS_PRESSURE as sum of ABS_MT_PRESSURE across all slots. This flag should be set if one knows a device reports true force and would like to report total force to the userspace.
