1	* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
2	
3	Required 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	
11	Optional 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.
14	
15	Examples:
16	
17	i2c@83fc4000 { /* I2C2 on i.MX51 */
18		compatible = "fsl,imx51-i2c", "fsl,imx21-i2c";
19		reg = <0x83fc4000 0x4000>;
20		interrupts = <63>;
21	};
22	
23	i2c@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	};
