From 872e57abd171515bc180f2d44c2c99da29542320 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 13 Oct 2021 13:23:05 +0200 Subject: Input: tm2-touchkey - allow changing keycodes from userspace At the moment the touch keys have key codes assigned from the device tree. In some cases, users might want to change the key code from userspace. There is existing functionality for this in the input core using the EVIOCSKEYCODE ioctl, which is integrated for example into udev. Make it possible to use this functionality for tm2-touchkey by simply making the input core aware of the array that holds the keycodes. Similar code also exists in mcs_touchkey and mpr121_touchkey.
