OK, sounds doable.

But you could easily remove all the board specific struct twl4030_codec_data
and struct twl4030_codec_audio_data entries by adding a default audio
init option to omap_pmic_init for the common configuration.

How about something like:

void omap_pmic_init(int bus, u32 clkrate, const char *pmic_type, int pmic_irq,
struct twl4030_platform_data *pmic_data, u32 flags);

Where flags would be TWL_BOARD_HAS_DEFAULT_CODEC etc, and if the entry in
pmic_data is NULL, just use the default configuration. I think you already
have the clkrate there?

Regards,

Tony
