From e6a90810559cc3755a5b1629d1fd0b914462f98c Mon Sep 17 00:00:00 2001 From: Bastian Hecht Date: Mon, 15 Apr 2013 09:31:00 -0700 Subject: Input: st1232 - add reset pin handling We add the possibility to hand over a GPIO number for the reset pin. This way we can remove existing board code that takes care of it and group this information properly in the platform data or in the device tree configuration.
