1、如何设置tlv320aic32x4为slave模式?
2、tlv320aic32x4芯片通过i2s接到高通soc芯片,高通芯片作为master设备,要输出多少的mclk呢?
3、linux驱动代码tlv320aic32x4.c中sysclk设置为多少,代码有有定义如下3个值,是否选择AIC32X4_FREQ_12000000?
#define AIC32X4_FREQ_12000000 12000000
#define AIC32X4_FREQ_24000000 24000000
#define AIC32X4_FREQ_25000000 25000000

MCLK ,Master Clock Input根据数据手册: 8.3 Recommended Operating Conditions
MCLK Master Clock Frequency
MCLK; Master Clock Frequency; DVDD ≥ 1.65VMax: 50MHz
MCLK; Master Clock Frequency; DVDD ≥ 1.26VMax: 25MHz

DVDD 约等于 1.68V ,MCLK 具体要设置为多少呢?数据手册只是列出了最大值。
还有,linux驱动代码中是否选择AIC32X4_FREQ_12000000?
