From 7854a5e094ac49bebf9b2bfdd44db2f8cdd37543 Mon Sep 17 00:00:00 2001
From: James Feist <james.feist@linux.intel.com>
Date: Fri, 31 May 2019 15:05:13 -0700
Subject: [PATCH] set idle-disconnect to true in all cases
From sysfs this parameter can't be set. We want the
muxes to clean themselves up if possible. Set this to
true.
