From 33096777519a66e632fed7f1e54e6480b4228827 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Fri, 27 Mar 2015 09:59:55 -0700 Subject: [PATCH] Input: define INPUT_PROP_ACCELEROMETER behavior Spell out what this property means to userspace. If the property is set, all directional axes must be accelerometer axes, any other axes are left as-is. This allows an accelerometer device to e.g. have an ABS_WHEEL. It is not permitted to mix normal directional axes and accelerometer axes on the same device node.
