Prefs
   1* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
   2
   3Required properties:
   4- compatible : Should be "fsl,<chip>-i2c"
   5- reg : Should contain I2C/HS-I2C registers location and length
   6- interrupts : Should contain I2C/HS-I2C interrupt
   7
   8Optional properties:
   9- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
  10  The absence of the propoerty indicates the default frequency 100 kHz.

  12Examples:
  13
  14i2c@83fc4000 { /* I2C2 on i.MX51 */
  15        compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
  16        reg = <0x83fc4000 0x4000>;
  17        interrupts = <63>;
  18};
  19
  20i2c@70038000 { /* HS-I2C on i.MX51 */
  21        compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
  22        reg = <0x70038000 0x4000>;
  23        interrupts = <64>;
  24        clock-frequency = <400000>;
