From 5c2cff85fc960f78546a6af2d9315849fab5e963 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Mon, 20 Jul 2015 15:17:18 +0200 Subject: [PATCH] sniper: Keypad support, with recovery and fastboot key combinations Using the twl4030 keypad allows booting directly into some special boot modes, such as recovery or fastboot. the VOL+ key will trigger a boot to recovery while the VOL- key will trigger a boot to fastboot. The G (gesture) key remains unused at this point.
