 * @reset_gpio: AC97 reset gpio (normally gpio113 or gpio95)
 *              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
 * AC97 reset line, which is the default on most boards.
