From 92a49871b378b1e523a95da569cd38efdd06eee5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 11 Jan 2013 08:55:39 +0900 Subject: extcon: arizona: Support use of GPIO5 as an input to jack detection Some system designs provide an input on GPIO5 which in conjunction with the jack detection feature indicates the presence of an accessory. Support such systems, using the microphone clamp feature to minimise wakeups of the processor.
