1* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
2
3Required properties:
4- compatible :
5 - "fsl,imx1-i2c" for I2C compatible with the one integrated on i.MX1 SoC
6 - "fsl,imx21-i2c" for I2C compatible with the one integrated on i.MX21 SoC
7 - "fsl,vf610-i2c" for I2C compatible with the one integrated on Vybrid vf610 SoC
8- reg : Should contain I2C/HS-I2C registers location and length
9- interrupts : Should contain I2C/HS-I2C interrupt
10
11Optional properties:
12- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
13 The absence of the propoerty indicates the default frequency 100 kHz.

15Examples:

17i2c@83fc4000 { /* I2C2 on i.MX51 */
18 compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
19 reg = <0x83fc4000 0x4000>;
20 interrupts = <63>;
21};
22
23i2c@70038000 { /* HS-I2C on i.MX51 */
24 compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
25 reg = <0x70038000 0x4000>;
26 interrupts = <64>;
27 clock-frequency = <400000>;
28};
