Subject: [PATCH 05/13] soundwire: intel: call helper to reset Slave states on resume
Date: Wed, 22 Jul 2020 04:37:15 +0800 [thread overview]
Message-ID: <20200721203723.18305-6-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20200721203723.18305-1-yung-chuan.liao@linux.intel.com>
From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
This helps make sure they are all UNATTACHED and reset the state
machines.
At the moment we perform a bus reset both for system resume and
pm_runtime resume, this will be modified when clock-stop mode is
supported
