From b8f0970d2c5a03f5a431d51af74dd1a0ec62fe91 Mon Sep 17 00:00:00 2001 From: Roderick Colenbrander Date: Fri, 24 Mar 2017 15:17:46 -0700 Subject: [PATCH] HID: sony: Improve navigation controller axis/button mapping The navigation controller is a DS3 (sixaxis) with fewer physical axes and buttons. It utilizes the same HID report as the DS3 and thus reports axes/buttons which aren't physically present. Currently many non-existing buttons and axes are reported, which we are now removing. For the axes/buttons which do exist, we make the axis/button mapping similar to the DS3.
