+ *              a -1 value means no gpio will be used for reset
+ * @codec_pdata: AC97 codec platform_data

+ * reset_gpio should only be specified for pxa27x CPUs where a silicon
+ * bug prevents correct operation of the reset line. If not specified,
+ * the default behaviour on these CPUs is to consider gpio 113 as the
