More flags are needed than will fit in the existing u8 flags member of omap_i2c_dev_attr. These flags can refer to options inside the IP block but they are most needed for information about cpu implementation specific options that are not part of the IP block itself. For example, how the CPU data bus is wired to the IP block databus differs between OMAP cpus and affects how you must shift the address in the IP block, but is not a feature of the IP block itself.
