From 2e2a390b7f6784d2409656f5ccf3433f4ec3e18d Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Tue, 27 Dec 2016 12:05:05 +0800 Subject: ASoC: rt5645: set sel_i2s_pre_div1 to 2 [ Upstream commit 02c5c03283c52157d336abf5e44ffcda10579fbf ] The i2s clock pre-divider 1 is used for both i2s1 and sysclk. The i2s1 is usually used for the main i2s and the pre-divider will be set in hw_params function. However, if i2s2 is used, the pre-divider is not set in the hw_params function and the default value of i2s clock pre-divider 1 is too high for sysclk and DMIC usage. Fix by overriding default divider value to 2.
