1  上电操作
   配置wm8960的上电脚，文件位置：arch/arm/mach-mx6/board-mx6q_sabresd.c

         #define SABRESD_CODEC_PWR_EN    IMX_GPIO_NR(7, 12)440     /* Enable wm8960 power supply */441     gpio_request(SABRESD_CODEC_PWR_EN, "audio-power");442     gpio_direction_output(SABRESD_CODEC_PWR_EN, 1);443     msleep(1);444     gpio_set_value(SABRESD_CODEC_PWR_EN, 1);445     printk("Power up wm8960 successful %s\n", __FUNCTION__);

另外，根据原理图可知上电脚为GPIO17，所以相关配置头文件里需将其配置为gpio口，文件位置：arch/arm/mach-mx6/board-mx6dl_sabresd.h

236     /* CODEC_PWR_EN */
237     MX6DL_PAD_GPIO_17__GPIO_7_12,

2：配置I2C，用于client的生成 ，文件位置：arch/arm/mach-mx6/board-mx6q_sabresd.c 需确认你的i2c是接的哪个控制器。

};
