Subject: [PATCH 4/4] sound: jz4740: Enable codec clock during dai_probe
Date: Mon, 26 Jan 2015 10:18:31 +0000	[thread overview]
Message-ID: <1422267511-6649-5-git-send-email-Zubair.Kakakhel@imgtec.com> (raw)
In-Reply-To: <1422267511-6649-1-git-send-email-Zubair.Kakakhel@imgtec.com>

As we are moving away from platform to DT, we cant rely on the board
file to do this now. So enable it here.
