From 41282920aa35033a4fcf2bc68aeba42a037e6c4d Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Fri, 24 Oct 2014 16:48:11 -0700 Subject: [PATCH] ASoC: fsl-asoc-card: Don't bypass settings if cpu-dai is Master When cpu-dai is the DAI Master (CBM_CFx), it may need some configurations, set_sysclk() call for eample, for cpu-dai side in the hw_params(), even if the set_bias_level() has already taken care of the codec-dai side. So this patch just simply adds an additional condition.
