From 6512dd4dcf640412637ece8a412e83c3a0046d2f Mon Sep 17 00:00:00 2001 From: Harsha Priya N Date: Thu, 27 Jul 2017 17:41:26 -0700 Subject: [PATCH] ASoC: Intel: Use MCLK instead of BLCK as the sysclock for RT5514 codec on kabylake platform This patch fixes the pop noise in dmic recording using rt5514 on kabylake platform. This patch enables the rt5514 to use MCLK instead of BLCK as the sysclock which fixes the pop noise.
