From aa6061a0d0032065e210789c52af5d9b0a375ba9 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Wed, 31 Jul 2013 23:40:55 -0700 Subject: kirby: pit: Fix up wakeup_need_reset In a previous commit the contents of wakeup_need_reset were removed because the GPIO it referred to wasn't connected to anything on pit. I didn't realize at that time that that could have been because we hadn't tried getting suspend/resume working on pit and hadn't updated that file. On snow, the GPIO is the recovery mode pin. This change updates pit to have the right GPIO, kirby to read that GPIO, and makes the comments for both pit and kirby more explicit and spells out the fact that this is the recovery mode GPIO. Having a check here at all may still be a holdover from snow that isn't applicable to pit or kirby, but since there is a parallel as far as the recovery mode GPIO we might as well make them match while waiting for more information.
