* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
Required properties:
- compatible : Should be "fsl,<chip>-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,imx1-i2c";
reg = <0x83fc4000 0x4000>;
interrupts = <63>;
};
i2c@70038000 { /* HS-I2C on i.MX51 */
compatible = "fsl,imx51-i2c", "fsl,imx1-i2c";
reg = <0x70038000 0x4000>;
interrupts = <64>;
clock-frequency = <400000>;
};
