There are two ways to define I2C_xxxx macros: gpio or direct SoC access
if you are using gpio to define macros, I think you get this warnings.
If you are using direct SoC access (no gpio driver needed) there are no warnings e.g.
#define I2C_ACTIVE writel(AT91_PMX_AA_TWD, &pio->pioa.mddr); #define I2C_TRISTATE writel(AT91_PMX_AA_TWD, &pio->pioa.mder); and so on

We need some volunteers, which convert the drivers.
