[U-Boot] Disabling CONFIG_DM_I2C_COMPAT in twl4030 PMIC

I am working to disable CONFIG_DM_I2C_COMPAT for the omap3 boards. Some of these boards use the TWL4030 PMIC which is still using the older i2c_write and i2c_read functions.

I wonder if someone can point me to a good patch that I can use a model one how to appropriately port I2C drivers forward? I'd like to disable this feature so the notice goes away since it seems like DM_I2C should be do-able by now.

thanks
