We are using Linux 3.10.45, imx6qdl-sabresd.dtsi config:

&i2c2 {

    clock-frequency = <400000>;   // i2c clock should be 400kbps

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_i2c2_2>;

    status = "okay";

 

    i2c devices...

 

}

 

But we check the board, and found the I2C2 SCLK is only 50Kbps.
