From 33d919bd51ad1203e86e3f60e775f463feb1586f Mon Sep 17 00:00:00 2001 From: PC Liao Date: Thu, 26 May 2016 20:50:50 +0800 Subject: [PATCH] ASoC: mediatek: Change the order of MCLK clock configuration Because MCLK opens later and closes earlier than codec, this patch changes the order of MCLK clock configuration.
