From b8575a1143f6d57a791c946291ba4363e07e32a3 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 7 Sep 2012 17:01:15 +0800 Subject: [PATCH] extcon: arizona: Use bypass mode for MICVDD We can perform microphone detection with MICVDD in bypass mode so try to enable that during startup for minimal power - other users or machine constraints will prevent bypass mode being activated if it is unsuitable.
