Kernel-3.10.0-957.el7_i2c-imx

  • Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX

Required properties:

  • compatible : Should be “fsl,-i2c”
  • reg : Should contain I2C/HS-I2C registers location and length
  • interrupts : Should contain I2C/HS-I2C interrupt

Optional properties:

  • clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
    The absence of the propoerty indicates the default frequency 100 kHz.

Examples:

i2c@83fc4000 { /* I2C2 on i.MX51 */
compatible = “fsl,imx51-i2c”, “fsl,imx21-i2c”;
reg = <0x83fc4000 0x4000>;
interrupts = <63>;
};

i2c@70038000 { /* HS-I2C on i.MX51 */
compatible = “fsl,imx51-i2c”, “fsl,imx21-i2c”;
reg = <0x70038000 0x4000>;
interrupts = <64>;
clock-frequency = <400000>;
};
