Subject: [PATCH 10/17] soundwire: add new mclk_freq field for properties
Date: Mon, 5 Aug 2019 19:55:15 -0500 [thread overview]
Message-ID: <20190806005522.22642-11-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20190806005522.22642-1-pierre-louis.bossart@linux.intel.com>
To help pass platform-specific values, add a new field that can either
be set by the Master driver or read from firmware (BIOS/DT).
