       i want to move a new tp chip into linux kernel 3.0.5  by i2c2 control .when i can not read any information form my i2c device (tp), so i test imx6 i2c2 control scl(gpio), but i can not find any wave in the i2c control scl gpio by oscilloscope。at last i change the i2c-imx.c file function :static int __init i2c_imx_probe(struct platform_device *pdev)
