int __init omap_register_i2c_bus	(	int	bus_id,
		u32	clkrate,
		struct i2c_board_info const *	info,
		unsigned	len
	)

omap_register_i2c_bus - register I2C bus with device descriptors : bus id counting from number 1 : clock rate of the bus in kHz : pointer into I2C device descriptor table or NULL : number of descriptors in the table

Returns 0 on success or an error code.
