All other drivers in drivers/i2c are host adapter drivers. Ie they implement i2c_read(), i2c_write(), i2c_probe(), and i2c_init(). The twl4030_i2c.c driver doesn't seem to fit this mold. Perhaps it would be better placed in drivers/misc or a new drivers/power directory similar to Linux?
This function probably belongs to board/omap3/common/power.c -> or even better to the board file itself? Regards, Nishanth Menon
